A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of:

A. 12 feet
B. 3 feet
C. 6 feet
D. 7.5 feet


Sagot :

To find the wave base of a wave, we use a specific relationship. The wave base is defined as the depth below the surface of the water where the orbital motion of the water particles is negligible. This depth is generally considered to be half the wavelength of the wave.

Given the wavelength of the wave is 15 feet, the wave base can be calculated as:

Wave base = (Wavelength) / 2

Substituting the given wavelength:

Wave base = 15 feet / 2

Simplifying this calculation:

Wave base = 7.5 feet

Therefore, the correct answer is:

D. 7.5 feet
