29
Q

Transverse wave

A

a wave that occurs when the particles of a medium are displaced perpendicularly to the direction of the wave

A wave in which the disturbance moves at right angles to the direction of the wave

30
Q

Mechanical Wave

A

a wave that is an oscillation of matter, and therefore transfers energy through a medium
