Question

Below what depth in meters would a submarine need to dive in order to avoid the potentially hazardous effect of waves with average wave length of 19 meters?

A) 10m
B) 5 m
C) 9.5 m
D) 9 m

Answer 1

A submarine needs to dive deeper than half the wavelength of ocean waves, which is 9.5 meters for waves with an average wavelength of 19 meters, to avoid their effects. Option C is correct.

Step-by-step explanation:

The question is asking at what depth a submarine would need to dive to avoid the influence of ocean waves that have an average wavelength of 19 meters. According to fluid dynamics, wave influence diminishes with depth, and is typically negligible below a depth equal to half the wavelength.

Therefore, the sub must dive below half the wavelength of the waves to avoid their effects. For waves with a 19-meter wavelength, the submarine would need to dive deeper than 9.5 meters, which is half the wavelength.

In order to avoid the potentially hazardous effects of waves with an average wavelength of 19 meters, a submarine would need to dive below half the wavelength of the waves. This means diving below 9.5 meters (half of 19 meters).

By diving below this depth, the submarine will be able to avoid the full force of the waves and minimize the impact on its operations.
