Bad reflectors of sound –
Thick curtains, thick carpets
.
What is a bad reflector?
Bad reflectors means
which do not reflect the sound clearly
. Are substances that reflect waves (sound, light, etc.). … Shiny and smooth surfaces tend to be characteristics of good reflectors of light waves. Such surfaces cause light to bounce (reflect) at the same angle in which the light hit the object.
Which of the following is an example for 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 is the good example of reflector of sound *?
Metal sheet and hardwood
are good reflectors of sound as they nearly reflect almost all the sound energy falling on it.
Why a cloth is poor reflector of sound?
yes, they are bad reflectors of sound
because they aren’t that tough
. Soft things can absorb sound and thus, clothes and curtains are bad reflectors of sound(because they absorbs the sound).
What is good reflector?
Reflectors are substances that reflect waves (sound, light, etc.). To “reflect” means to “bounce back”. … Therefore, substances that could be listed on the “good reflectors” side of your table are:
metals (aluminum, copper, silver, gold, spoons, etc) and mirrors
.
Is mirror a good reflector of sound?
A mirror is
an excellent reflector of sound waves
but the frequencies reflected are very much depending on the size and the thickness of the mirror. Small objects can only reflect sounds with a wave length similar or smaller than the given object. So a small mirror will only reflect high frequencies.
Is Wall a good 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 materials can reflect sound?
- Marble.
- Granite.
- Clay Brick.
- Ceramic Tile.
- Smooth Concrete.
- Plaster.
- Metal.
- Glass.
Is Wall a good reflector?
A
Wall Mirror
A big mirror
is also a good reflector, besides being a good base to photograph things like jewelry. It reflects light and it doubles the image of the object for some interesting compositions. A wall mirror or any big mirror you can use as a base for photographing small objects is a good choice.
Which is the best absorber of sound?
Answer:
Wool
is the best absorber of sound.
What is the space where sound waves are unable to travel?
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.
Does sound slow down in water?
How does sound going slower in water make it hard to talk to someone underwater?
Sound travels faster in water than in
air. The speed of sound in air under typical conditions is about 343 meters per second, while the speed of sound in water is about 1,480 meters per second.
Why do hard surfaces reflect sound and soft surfaces absorb sound?
The
hard surfaces reflect the sound waves better than the soft surfaces
. This is because the sound waves can not penetrate the hard surfaces easily, while the soft surfaces absorb the sound waves.
What do you mean by reflection of sound?
Bouncing back of sound waves from the surface
is called reflection of sound or we can say that when sound travels in a given medium it strikes the surface of another medium so that it returns in some other direction, this phenomenon is called reflection of sound.
Which of the following surfaces is a poor absorber of sound?
Soft surfaces
are poor reflector of sound.
