Which one of the following statements is true for sound waves propagating in air ?

Options

  1. ASound is an electromagnetic wave and transverse in nature
  2. BSound is a mechanical wave and longitudinal in nature
  3. CSound is a mechanical wave and transverse in nature
  4. DSound is an electromagnetic wave and longitudinal in nature

Correct answer

B. Sound is a mechanical wave and longitudinal in nature

Step-by-step solution

Sound is a mechanical wave because, sound can not propagate without medium and Sound waves are longitudinal because A longitudinal wave is one where all the particles of the medium (such as gas, liquid or solid) vibrate in the same direction as the wave.
