Questions and Answers

What distribution is used to describe wave heights in deep water when waves are not too steep?

Rayleigh distribution (correct)

Exponential distribution

Uniform distribution

Normal distribution

What is the probability density function for the Rayleigh distribution of wave heights?

$p(H) = \dfrac{H}{4\sigma} e^{-\tfrac{H^2}{8\sigma^2}}$

$p(H) = \dfrac{H}{2\sigma^2} e^{-\tfrac{H^2}{8\sigma^2}}$

$p(H) = \dfrac{H^2}{4\sigma^2} e^{-\tfrac{H}{8\sigma^2}}$

$p(H) = \dfrac{H}{4\sigma^2} e^{-\tfrac{H^2}{8\sigma^2}}$ (correct)

In practice, what is often ignored when considering the wave heights' distribution?

Wave steepness

Wave refraction

Wave period variability (correct)

Wave interference
