The frequency of a wave depends on the medium. For example, the sound wave moves with different frequency in air and in water     Electromagnetic wave is a longitudinal wave     The speed of a wave depends on the medium. For example, the sound wave moves at different speed in air and in water     All electromagnetic waves move at the speed of light in vacuum     Electromagnetic wave is a transverse wave
