Solution

The correct option is B
False

The law of reflection of sound states that the directions in which the sound is incident and reflected make equal angles with the normal to the reflecting surface and the three lie in the same plane.

Mark the correct statement:

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 a rough surface

11. Which of the following statements given is/are correct?

1. Sound gets reflected at the surface of a solid or liquid and follows the same laws of reflection as Light.

2. The directions in which the sound is incident and is reflected make unequal angles with the normal to the reflecting surface

The angle of incidence and angle of reflection are equal only if the incident ray and the reflected ray are in the same plane and the normal is in a different plane.

Q. State true or false.
The angle of reflection equals to the angle of incidence, only holds true for the light wave but not for a sound wave.

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.
