Question

what are good and bad reflectors of sound give two examples each​

Answer 1

GOOD REFLECTORS OF SOUND:

• These are materials which are able to reflect majority of the sound wave well with minimum amount of sound energy being absorbed.

• Examples are : Mylar (>98% reflectivity), Aluminium foil (~88% reflectivity), Acrylic mirrors, etc.

BAD REFLECTORS OF SOUND:

• These are materials which reflect sound very bad and absorb most of the sound energy within itself. Hence, these materials have very low reflectivity.

• Examples : Concrete surfaces, curtains, leather, etc.

Answer 2

The good and bad reflectors of sound are as follows-

1. Good reflectors of sound: It includes objects or materials that reflect the majority of the sound waves that reach their surface and absorb only a small amount.

For example- Metals, glass

2. Bad reflectors of sound: It includes objects or materials that are incapable of reflecting the sound waves effectively and absorb most of them.

For example- Thermocol, concrete
