A flat mirror is a nearly perfect reflector for light – the amount of energy in the reflected wave is equal to the amount of energy in the incident wave.
The underside of the ocean surface
is a nearly perfect reflector for sound under calm conditions, particularly at low frequencies.
Do mirrors reflect or absorb sound?
a
mirror may reflect sound
, but a much smaller ratio as it reflects light. In reflecting the sound, some of it is absorbed because the energy from sound is mechanical in nature, translating from the air to the mirror much more readily than light, which is generally not absorbed at all.

Are mirrors good for acoustics?
Parabolic acoustic mirrors
are widely used in parabolic microphones to pick up sound from great distances, employed in surveillance and reporting of outdoor sporting events. Pairs of large parabolic acoustic mirrors which function as “whisper galleries” are displayed in science museums to demonstrate sound focusing.
What happens when sound hits a mirror?
Smooth surfaces produce strong echoes
when sound waves hit them, and they can act as mirrors when light waves hit them. The waves are reflected uniformly and light can form images. … appear to come from a point behind the mirror, eg a looking glass.
Which is a bad reflector of sound?
Answer: The objects which reflect sound and have a hard and smooth surface are good reflectors of sound. The
objects which do not reflect sound and are soft and porous
are bad reflectors of sound.
What medium can sound not travel through?
Sound cannot travel through
a vacuum
. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
Where do you put acoustic panels in a room?
- Place acoustic panels at the first place on the wall where sound waves tend to hit before reaching the listeners ears.
- Place 3′ to 6′ up from the floor in areas where much of the sound is produced by people sitting or standing in enclosed spaces.
When you look at your face in a mirror where does your face appear to be?
The image of your face appears to be
behind the mirror
. Indeed the farther you step back away from the mirror, the farther behind the mirror the image is.
How do you find your first reflection point by yourself?
Early reflection points or first reflections are terms to
describe direct sound which arrives at the listener's ears before the rest of the reflected sound does
. Sound reflects not just off the walls to the left and right, but off the floor, the ceiling and everything in-between.
What happens to sound when it hits a surface?
Sound is
bounced off a surface
. This usually occurs on flat, rigid surfaces with a lot of mass like concrete or brick walls. Because the sound wave can't penetrate very far into the surface, the wave is turned back on itself like a ricochet. The sound bouncing back off the surface creates an echo.
What happens when sound hits a rough surface?
If the surface that the sound wave hits is relatively smooth,
more sound will be reflected than if the surface is rough
. … The reason is that the rough or porous surface allows for many internal reflections, resulting in more absorption and less reflection.
How do you reflect sound?
- Marble.
- Granite.
- Clay Brick.
- Ceramic Tile.
- Smooth Concrete.
- Plaster.
- Metal.
- Glass.
Which is the best absorber of sound?
Answer:
Wool
is the best absorber of sound among the given options.
Which of the following is the best reflector of sound?
Walls of aroom
are good reflectors of sound. Wood, carpets, curtains, clothes and even our bodies absorb sound better and reflect less. In fact, soft surfaces are better absorbers of sound whereas hard surfaces are better reflectors of sound.
What makes a good reflector?
Smooth, light coloured, or shiny surfaces like glass, water and metal
are excellent reflectors. All the light that hits them bounces back off. We say they are highly reflective. Mirrors.
