It bounces back.
When a sound hits a flat surface it bounces back in exactly the same direction as before, in exactly the same frequency and pitch.
What happens when sound hits a thin membrane is that it vibrates the tympanic membrane. The tympanic membrane is also known as the eardrum.
no. it's absorbed
They are reflected :)
Sound is just a mechanical vibration of the particles which flows in all directions away from the source. It can be reflected from objects or be absorbed...it depends on the type of material, and also its surface - probably a soft material with complicated surface, like wool, or cushion will absorb most of the sound, whereas a hard, compact object with a glazed surface, like glass or concrete, will reflect more.
They are either absorbed [softsurface, e.g. wool] or refected [hard surface, e.g. metal]
when light hits a rough surface it scattters.
i thing it produces sound?
Sunlight that hits the Earth's surface is absorbed by the Earth. It is then reflected back.

no. it's absorbed
generally speaking, the sound is absorbed.
They are reflected :)
im assuming that u meant "what happens when LIGHT hits a black surface?" the reason for this is that the black surface ABSORBS the light, and so none of the light waves can be reflected back (which is what makes it look black)

Because of acoustics-- when a sound hits a flat surface, it bounces off. If that surface is curved one direction, sound will travel that direction. If sound resonates to a dome surface bent outward to the audience, naturally the sound will move the direction that the dome is facing when the sound bounces off of the surface. <3 Luv Clo
