Question

a hard and flat surface is good reflector of the sound true or false​

Answer 1

Answer:

I think your ans is true

Answer 2

The statement is true.

• Sound is easily and completely reflected from a hard and flat surface. The surface will not absorb energy from the sound wave and there is complete reflection.
• A soft surface will absorb most of the energy and reflects very little.
• To produce an echo, the sound waves should travel through a certain distance (atleast 17m) and hit a hard and flat surface. A very large distance or an irregular surface is present, the sound will not form a proper echo.
