Question

to study of reflaction of sound​

Answer 1

Explanation:

Sound. To verify the laws of reflection of sound. Sound: It is a form of energy produced by vibration and it needs medium to propagate. Reflection of sound: As light reflects when it strikes any hard object (opaque), sound also gets reflected when it strikes any object.

Answer 2

Answer:

The angle of incidence is always equal to angle of reflection and the normal at the point of incident comes at 90°and also reflects at 90°

The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.

Explanation:

The law of reflection governs the reflection of light-rays off smooth conducting surfaces, such as polished metal or metal-coated glass mirrors
