JAMB - Physics (2019 - No. 84)
Which of the following statements are correct of the production and propagation of waves?
I. vibration produces waves
II. waves transmit energy along the medium
III. the medium through which the wave travels does not travel with the wave
IV. waves do not require any medium for transmission
I. vibration produces waves
II. waves transmit energy along the medium
III. the medium through which the wave travels does not travel with the wave
IV. waves do not require any medium for transmission
I & IV only
II & IV only
III & IV only
I, II and III only
Explication
- Waves are produced by vibration
- Waves transmit energy along the medium
- Particles of a medium vibrate with the wave motion without the entire medium
- Some waves require medium for transmission (mechanical).
