Question

An ocean wave with a length of 800 m will first be considered a deepwater wave at

what depth? Hint: remember L and d relationship for deepwater waves.

Answer 1

An ocean wave with a length of 800 meters is considered a deepwater wave when the ocean depth exceeds 400 meters, which is more than half of its wavelength.

Step-by-step explanation:

An ocean wave will first be considered a deepwater wave at a depth that is greater than half its wavelength. Given that the wavelength (L) of the ocean wave is 800 meters, a deepwater wave occurs at a depth where d > L/2 which, in this case, means the depth must be greater than 400 meters. So, the ocean depth needs to be more than 400 meters for the wave with a length of 800 meters to be considered a deepwater wave.
