Chapter 12, Problem 5RAT

The vibrations along a longitudinal wave move in a direction

(a) parallel to the wave direction.

(b) perpendicular to the wave direction.

(c) Both of these.

(d) Neither of these.

To determine

The correct option for the statement “The vibrations along a longitudinal wave move in a direction”.

Answer to Problem 5RAT

The correct option for the statement “The vibrations along a longitudinal wave move in a direction” is option (a).

Explanation of Solution

Any object is said to be in vibration when it undergoes uniform motions back and forth, side to side, or up and down. A wave is an array of particles with vibrations carried through space and time. The wave is a pattern of matter or energy that extends from one place to another.

A longitudinal wave is defined as the direction of wave travel is along the direction in which the source vibrates. The vibrations are then parallel to the direction of energy transfer. It is in the transverse waves that the vibrations are perpendicular to the wave motion.

Conclusion:

Therefore, the correct option for the statement “The vibrations along a longitudinal wave move in a direction” is option (a).
