Question

A string of length 2.5 m is fixed at both ends. When the string vibrates at a frequency of 85 Hz, a standing wave with five loops is formed. Determine the velocity of waves.

Answer 1

The velocity of waves can be calculated using the equation v = fλ, where v is the velocity of the wave, f is the frequency of the wave, and λ is the wavelength of the wave. In this case, the frequency is 85 Hz and the wavelength is 2.5 m. Therefore, the velocity of the wave is 212.5 m/s.
