Which of the following wave properties is the best way for surfers to judge how fast waves are coming in to shore?
amplitude
frequency
equilibrium
trough

Answer;

-Frequency

Explanation

-Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.

-The speed of a wave is dependent on four factors: wavelength, frequency, medium, and temperature.  Wave speed is calculated by multiplying the wavelength times the frequency. Since speed is constant within the same medium, a high frequency has a short wavelength and vice-a-versa
