which of these events is an example of the doppler shift? the amplitude of a wave on a string increases as the frequency decreases. the amplitude of sound from a tuning fork decreases due to damping. the frequency of light from a star increases as it moves toward us. the intensity of an electromagnetic wave increases with the field strength. the velocity of an electromagnetic wave changes as its medium changes.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
