Awave propagates at a well defined velocity that depends on the properties of the medium that carries the wave. true or false?

True

Explanation:

A wave is generated as a result of oscillations which creates disturbances in the medium and these disturbances termed as waves propagates or travels from one point to another.

Waves can be classifies as:

Mechanical waves which requires material medium for their propagation

Electromagnetic waves which do not require any material medium to propagate.

A wave travels at a specific velocity depending on the type of the medium in which it propagates.
