Solution

The correct option is A
a. 1 only

Answer-a

Like light, sound gets reflected at the surface of a solid or liquid and follows the same laws of reflection. The directions in which the sound is incident and is reflected make equal angles with the normal to the reflecting surface at the point of incidence, and the three are in the same plane.

Q. Mark the correct statements.
(I) directions in which the sound is incident and is reflected make equal angles with the normal to the reflecting surface.
(II) reflection of sound occurs from a polished surface.
(III) reflection of sound occurs from rough surface.

The direction in which the sound is incident and reflected makes equal angles with the normal to the reflecting surface, but the three are not in the same plane.

Q. Like light, sound also gets reflected at certain surfaces and it follows laws of reflection.

Q. Does reflection of sound also undergoes the laws of reflection.
Laws of reflection state s that incident ray normalray reflected ray and emergent ray will lie in a same plane ,2. Incident ray is equal to reflected ray.and this is true in reflection of light .is it relative to reflection of sound?

Q. In which of the following cases, the force due to the incident radiation will be largest? Assume same intensity and surface area for all cases.

(1)

Radiation incident normally on a surface, getting absorbed completely.

(2)

Radiation incident normally on a surface, getting reflected completely and travelling in opposite direction with same speed.

(3)

Radiation incident obliquely on a surface, getting reflected completely and travelling with same speed, after reflection.
