A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of 7.5 feet.
A. 7.5 feet
Step-by-step explanation:
Wave base defines the depth of the water when it is in still condition.
Wave base is half of wavelength.
Wave base = wavelength/2
Given,
Wavelength = 15 feet
So, wave base = 15 feet/2 = 7.5 feet
When the wave height is divided by wavelength then it gives the steepness of the wave.
Therefore, the wave base is 7.5feet.
