The correct answer is D. 2200 Hz
Explanation:
The frequency of a wave is measured in hertz (Hz) and refers to how often a wave passes through a point during a specific time. This factor can be calculated if you divide the velocity of the wave by the wavelength (distance between crests) this means f (frequency) = v (velocity) / λ (wavelength).
f (frequency) = 242 m/s (velocity) / 0.11 (wavelegth)
f = 2200 Hz
According to this, the frequency of the wave, in this case, is 2200 Hz
