The velocity of the wave having a frequency of 458 Hz and a wavelength of 0.74 m is 338.92 m/s
The velocity of a wave is related to its frequency and wavelength according to the following equation:
Velocity (v) = wavelength (λ) × frequency (f)
v = λf
v = λf
v = 0.74 × 458
v = 338.92 m/s
Thus, the velocity of the wave is 338.92 m/s
