Answer :
The velocity of the wave with a frequency of 23.0 Hz and a wavelength of 14.9 m is 343 m/s.
The velocity of a wave can be calculated using the formula: velocity = frequency × wavelength. In this case, the given frequency is 23.0 Hz, and the wavelength is 14.9 m.
Substituting these values into the formula, we have: velocity = 23.0 Hz × 14.9 m.
To find the product, we multiply the frequency and the wavelength: velocity = 341.7 m/s.
Rounding the result to three significant figures, the velocity of the wave is approximately 343 m/s.
Therefore, the correct answer is 343 m/s. The other options listed (1.54 m/s, 8.1 m/s, 37.9 m/s) are not consistent with the calculated velocity based on the given frequency and wavelength.
