The concave reflector of sound is called echo.
Explanation:
- An echo happens when a sound wave is reflected out of the surface, such as the water from the bottom of wells, and the sound is repeated back to you.
- The sound waves would be able to bounce the smooth off. It had hard objects in the similar way like a rubber ball which bounces above the ground.
- Any concave surface will tend to focus on the sound waves which reflect from it.
- The concave surfaces have tendencies to focus on the sound waves, hence they are concentrating the sound in specified areas.
