The formula for wave speed (v) is wavelength (λ) multiplied by frequency (f), or v=λf. Rearranging this formula to solve for frequency, we get f=v/λ.
Using the given values, we can calculate the frequency as:
f = 400 cm/s / 100 cm = 4 Hz
Therefore, the frequency of the surface wave is 4 Hz. Answer: 4 Hz.
Using the given values, we can calculate the frequency as:
f = 400 cm/s / 100 cm = 4 Hz
Therefore, the frequency of the surface wave is 4 Hz. Answer: 4 Hz.
