WHAT IS SOUND ? A MECHANICAL WAVE ?

Introduction to Sound Wave || Equation OF Sound Wave

What is the difference between a sound wave and a T. V. wave ?

What is the evidence in support of the fact that (a) sound is a wave (b) sound is a mechanical wave (c) sound waves are longitudinal.

Do interference effects occur for sound waves ? Recall that sound is a longitudinal mechanical wave while light is transverse and non- mechanical ?

(A ): The light can travel in vacuum but sound cannot do so (R) : Light is an electromagnetic wave and sound is a mechanical wave

(A ): The light can travel in vacuum but sound cannot do so (R) : Light is an electromagnetic wave and sound is a mechanical wave

Assertion: Light can travel in vacuum but sound cannot do so. Reason: Light is an em wave and sound is a mechanical wave.
