Answer 2

ANSWER
__________


Sound is a form of energy, that form of energy which makes us hear. Sound is produced because of the presence of vibrations in the object. If the frequency of vibration is less then we will hear a fainting sound and if the frequency of vibration is more then we will hear a loud sound. Sound with regular vibrations are considered to be music whereas sound with irregular vibrations are considered to be noise.


Light is a form of energy, that is needed to see things around us. The objects which emit light of their own are known as luminous objects. The objects which do not emit light of their own are known as non-luminous objects.
Light passes through transparent objects clearly like glass and air. Only a little light passes through translucent objects like butter paper and paraffin wax. No light passes through opaque objects like wood and milk. Light is produced through electromagnetic radiations.
