what do light waves oscillate
In longitudinal  waves, we cannot limit longitudinal motion without actually  blocking the wave.    Picture two transverse waves that are moving in the same  direction. One is moving up and down as it travels and the other is  moving side to side.ecause transverse waves like electromagnetic waves (light) move  side to side when the travel, and we can limit the side-to-side  motion of a wave, and still allow the wave â¦ to pass.
