COMEDK · Physics · 16. Waves and Sound
Sound waves in air are always longitudinal because
- A air is a mixture of several gases
- B density of air is very small
- C of the inherent characteristics of sound waves in air
- D air does not have a modulus of rigidity
Answer & Solution
Correct Answer
(D) air does not have a modulus of rigidity
Step-by-step Solution
Detailed explanation
Air is a completely elastic medium, i.e. it does not have modulus of rigidity, therefore sound wave in air are always longitudinal.
