Physics 2017 JAMB Past Questions - Question 14: Transverse waves can be distinguished from longitudinal wave using the characters of

Correct Answer

C

Explanation

Transverse waves and longitudinal waves can be distinguished based on their characteristics. Here are some key differences:

1. Direction of Particle Motion: In a transverse wave, the particles of the medium vibrate perpendicular (at right angles) to the direction of wave propagation. In contrast, in a longitudinal wave, the particles vibrate parallel to the direction of wave propagation.

2. Wave Shape: Transverse waves have crests (peaks) and troughs (valleys) that are perpendicular to the direction of wave travel. On the other hand, longitudinal waves have compressions (regions of high pressure) and rarefactions (regions of low pressure) that are parallel to the direction of wave travel.

3. Energy Transfer: Transverse waves transfer energy by causing the particles of the medium to move up and down or side to side. Longitudinal waves, on the other hand, transfer energy by causing the particles of the medium to compress and expand in the same direction as the wave.

4. Examples: Transverse waves can be observed in phenomena such as light waves, water waves, and electromagnetic waves. Longitudinal waves can be observed in sound waves and seismic waves.

These characteristics can help differentiate between transverse and longitudinal waves.
