Question

In a _____________ wave, vibrations are perpendicular to the direction of the wave motion. In a _____________ wave, vibrations are parallel to the direction of the wave motion.

Answer 1

parallel are longitudinal waves. perpendicular are transverse waves. so the answer is in a transverse waves vibrations are perpendicular . in longitudinal wave vibrations are parallel

Answer 2

The answer will be, “TRANSVERSE wave and LONGITUDINAL wave."

The transverse and longitudinal are on the basis of the particles of the medium that they are travelling through.

These waves help in giving the proper result to the change in vibration.

Also, the result can change as per the medium such as water, air, etc.
