	Doppler effect - Wikipedia, the free encyclopedia
		For waves, such as sound waves, that propagate in a wave medium, the velocity of the observer and the source are reckoned relative to the medium in which the waves are transmitted.
		For waves which do not require a medium, such as light or gravity in special relativity only the relative difference in velocity between the observer and the source needs to be considered.
		A radar beam is fired at a moving target - a car, for example, as radar is often used by police to detect speeding motorists - as it recedes from the radar source.

	Waves
		of a wave is the distance from a crest to where the wave is at equilibrium.
		Once a wave (incident wave) has reached the end of a medium, part of the energy is transferred to the medium that is immediately next to it (transmitted wave) and part is reflected backward (reflected wave).
		The angle between the incident wave and the normal is the same as the angle between the normal and the reflected wave.

		Waves are an expression of the universal rhythm that orchestrates and propels all creation and the development of life on earth.
		Ocean waves are among the earth's most complicated natural phenomena, yet when we picture waves in the abstract, our minds might conjure an image of the perfect concentric ripples that echo the point of entry of a pebble into smooth pond waters.
		If the water were moving with the wave, the ocean and everything on it would be racing into the shore with catastrophic results.

		Waves are identified by the relationship between the motion of the disturbance and the motion of the medium.
		Transverse waves are waves in which the motion of the particles in the medium is perpendicular to the direction of motion of the disturbance.
		For a sinusoidal wave the wavelength and frequency are related to the speed of the wave in the medium.

		The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer.
		As the car approached with its siren blasting, the pitch of the siren sound (a measure of the siren's frequency) was high; and then suddenly after the car passed by, the pitch of the siren sound was low.
		For these reasons, if the source is moving towards the observer, the observer perceives sound waves reaching him or her at a more frequent rate (high pitch); and if the source is moving away from the observer, the observer perceives sound waves reaching him or her at a less frequent rate (low pitch).

	TEW--The Theory of Elementary Waves
		Indeed, by reciprocity, the intensity of the wave reaching the source from a point on the screen is identical to the intensity of the usual forward moving quantum wave reaching that point on the screen, assuming identical intensity upon emission.
		Wave entanglements are generally viewed as being essential to the description of identical particle phenomena and to the entire structure of quantum mechanics; so it may strike the reader as absurd to try to account for multi-particle effects without them.
		Because the (anti-)photon moves in the opposite direction, it is emitted, in effect, in response to a wave coming from the direction of the photon source-a wave, that is, which is moving along with the initial photon.

	Water Waves
		Thus, the velocity (speed) of a wave is not at all the same as the velocity of the water.
		As the waves slow, their profile (Figure on left) is laterally compressed and since each wave must carry the same energy it becomes higher.
		This wave moves at the speed of the boat and its wavelength with the square root of the speed.

	10(ac) Coastal and Marine Processes and Landforms
		Where ocean depths are greater than the length of the waves, the wave motion does not extend to the ocean floor and therefore remains unaffected by the floor.
		Waves are subject to a reorientation, or wave refraction of their direction of travel as they approach the coast.
		The wave crests are shown approaching the shore perpendicular to the general trend of the coast.

	Plane Standing Waves
		Two sets of waves will add their amplitude, and this means that while the phase is adding constructively, the energy is four times higher there.
		One should realize that while standing waves are present, the medium does not behave in the same manner as for traveling waves.
		This means that moving at.5 c a clock on the Moon should be about.666 second late if they were in the front of the moving frame of reference.

	The Doppler Effect
		The net effect of the motion of the bug (the source of waves) is that the observer towards whom the bug is moving observes a frequency which is higher than 2 disturbances/second; and the observer away from whom the bug is moving observes a frequency which is less than 2 disturbances/second.
		The Doppler effect is observed whenever the source of waves is moving with respect to an observer.
		can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching and an apparent downward shift in frequency for observers from whom the source is receding.

		The longer the period, the faster the waves are moving.
		But in fact, a wave is motion moving through a body of water; most of the water where it is. When wind and water meet, the result is waves—that may seem obvious.
		Big wind waves move away from the storm that created them, just like the waves in your bathtub move away from you as you blow on the water.

	NASA/Marshall Solar Physics
		Sound waves are produced by pressure fluctuations in the turbulent convective motions of the sun's interior.
		Inward moving waves are refracted (their direction of motion bent) by the increase in the speed of sound as the temperature increases and eventually return to the surface.
		These sound waves, and the modes of vibration they produce, can be used to probe the interior of the sun the same way that geologists uses seismic waves from earthquakes to probe the inside of the earth.

	Ground and Sky review - Focus - Moving Waves
		That said, Moving Waves is certainly not a bad album, and should appeal to symphonic prog fans.
		Waves of piano and fragile flute, played to bittersweet perfection to fully capture the melancholy of the Greek mythology character for which it is named.
		The lyrics are very awkward ("Moving waves / what motive is behind your impulse?") and, again, the song sounds more like a fragment of something else than its own entity.

		The blue wave is moving to the right and the green wave is moving to the left.
		Standing waves are produced whenever two waves of identical frequency interfere with one another while traveling opposite directions along the same medium.
		In conclusion, standing wave patterns are produced as the result of the repeated interference of two waves of identical frequency while moving in opposite directions along the same medium.

	Cover Art: Focus - Moving Waves
		A few words contributed by Frits Barth: The Moving Waves album was originally released in the Netherlands with a different cover and was called FOCUS II.
		The five movements on side 2 are divided in 15 movements instead of the five times three on the cover of Moving Waves.
		The back cover of Moving Waves contains the same photograph asthe Focus II back cover, only that one is in fl and white.

	FOCUS Moving Waves reviews and MP3
		Le Clochard, Janis, Moving Waves and Focus II are all melodic compositions an incorporate many classical passages (both guitarist Akkerman and Flutist/keyboardist Van Leer had classical training).
		Moving Waves is a very good point to begin for those who don't know this dutch band.
		Many people consider Moving Waves as the "Non Plus Ultra" Focus release, something with what I don't agree because Hamburger Concerto is slightly better and more mature, despite this fact Moving Waves is an excellent album, but also for different reasons than most people consider.

		When the charge moves at relativistic speed, the electric field is concentrated near the pole, and consequently the field lines are shifted.

		The album that boosted Focus into at least semi-fame outside of continental Europe, Moving Waves blasts off with their hit single, "Hocus Pocus." Built around a killer guitar hook by Jan Akkerman and a series of solo turns by the band, this instrumental replaced "Wipeout" as a staple of FM radio.
		The bizarrely hilarious vocal and accordion solos by Thijs van Leer -- one of which absurdly concludes with rousing stadium cheers -- have to be heard to be believed.
