Question

The diagram below shows the displacement-time graph for a vibrating body.

1. Name the type of vibrations produced by the vibrating body. 

2. Give one example of a body producing such vibrations. 

3. Why is the amplitude of the wave gradually decreasing? 

4. What will happen to the vibrations of the body after some time?

Answer 1

1. Transverse vibrations are produced which are gradually damped. 

2. A stretched string of a guitar. 

3. As the energy of wave is dissipated its amplitude decreases. 

4. The body will stop vibrating. It will come to rest.
