The amplitude of a paricular wave is 4.0 m. The crest to trough distance would be...
1. 8.0 m
2. 2.0 m
3. 4.0 m
4. 16.0 m

The crest to trough distance = 8 m

Explanation:

Given that,

The amplitude of a particular wave is 4.0 m.

We need to find the crest to trough distance.

We know that,

Amplitude = The distance from the base line to the crest or the the distance from the baseline to the trough.

It means,

Distance from crest to trough = 2(Amplitude)

= 2(4)

= 8 m

Hence, the crest to trough distance is equal to 8 m.
