NEET Physics Question - Wave Optics

Assertion (A): Two persons separated by a \(7\text{ m}\) partition wall in a room of \(10\text{ m}\) high can heard each other easily but cannot see each other.

Reason (R): Any sound wave can bend by the obstacle while light can't.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is true. This is a common observation due to the differing wavelengths of sound and light.
Reason (R) is true. Sound waves have longer wavelengths than light waves, causing them to diffract (bend) significantly around common obstacles. Light waves also diffract, but negligibly so for large obstacles like walls.
Reason (R) correctly explains Assertion (A).
