Question

A mechanical wave is a wave that __________ its energy.

does not require a medium to transfer

does require a medium to transfer

does not transfer

Answer 1

A mechanical wave does not need a medium, but they can travel through one.

Answer 2

Answer : A mechanical wave is a wave that does not require a medium to transfer its energy.

Explanation :

A wave creates a disturbance in a medium. The wave can be of many types like the mechanical wave, electromagnetic wave etc.

The electromagnetic wave does not require any medium for the transportation of energy.

The mechanical wave is the wave that requires a medium to transfer energy.

There are two types of mechanical wave :

• Longitudinal wave

• Transverse waves

Hence, the correct option is (A) "does not require a medium to transfer".
