To determine: The speed of the waves
Answer: The speed of the waves is 10.8 ms-1.
Explanation:
Given info: The wavelength of the waves is 38 m. The number of waves passing per minute is 17.
The formula to calculate the frequency of the waves is,
Thus calculate the number of waves per sec,
The formula to calculate the velocity of the surfer is
Here,
v is the speed of the wave.
f is the frequency of the waves
λ is the wavelength of the wave.
Substitute 0.283Hz for f and 38 m for λ in the above equation.
Conclusion:
Therefore, the velocity of the waves is 10.8 ms-1.

- Radio waves are electromagnetic waves that travel at a speed of 3.00 x 10^8 m/s, the speed of light. An AM radio station has an assigned frequency of 601 kHz, which means that the radio waves broadcast by the station are at this frequency. Find the wavelength of these radio waves.
