Answer:
hey u apply p=mv and 2 are given then calculate thirds value it's a simple do it
Sound waves are mechanical waves while electromagnetic waves are not. Thus, sound waves require a medium for propagation while electromagnetic waves do not. Sound waves are produced by mechanical vibrations and propagate through liquid, air and plasma as longitudinal waves. While electromagnetic waves are <span>produced by </span>accelerating or decelerating<span> charged particles. It also contain a</span> <span>magnetic field. Because they are not mechanical waves, it can propagate through a vacuum as well as air, liquid, and solid.</span>
