the answer is B. 72 </span>
Answer: Frequency = 15Hz
Explanation:
Given that
Wavelength (λ) = 3 m
Wave speed V = 45 m/s
Wave speed is the product of frequency and wavelength. That is
V = f(λ)
Substitute wavelength and wave speed into the formula
45 = f × 3
Make f the subject of the formula
f = 45/3
f = 15 Hz
Therefore, the frequency of the ocean wave is 15 Hz
