Chapter 14, Problem 81A

To determine

The waves produced due to in the bar due to the hitting the bar by hammer along and perpendicular to bar.

Explanation of Solution

Introduction:

The waves are categorized on the basis of the movement of the particle. The movement of the particle may be along or normal to the movement of the particle.

When the bar is hit by hammer along the length of the bar, the motion of the particle remains along the length of the bar, so the wave produced in this case is longitudinal waves.

When the bar is hit by hammer right angle to the length of the bar then the motion of the particle remains normal to the length of the bar. So, the wave produced in this case is transverse waves.

Conclusion:

Therefore, the wave produced along the length of the bar is longitudinal wave and at right angle to the length of the bar is transverse wave.
