A tuning fork produces a sound wave with a wavelength of 0.20 m and a velocity of 25.6 ms What is the frequency of the tuning fork?

To find the frequency of the tuning fork, you can use the formula ( f = \frac{v}{\lambda} ), where ( f ) is the frequency, ( v ) is the velocity of the wave, and ( \lambda ) is the wavelength. Plugging in the values, ( f = \frac{25.6 , \text{m/s}}{0.20 , \text{m}} = 128 , \text{Hz} ). Therefore, the frequency of the tuning fork is 128 Hz.
