Given:
The frequency of the generator is f = 10 pulses per second
The speed of the wave is v = 300 m/s
Required: The wavelength of the wave
The change in wavelength if the frequency of the pulses is increased.
Step-by-step explanation:
The wavelength of the wave can be calculated by the formula

On substituting the values, the wavelength of the wave will be

The wavelength is inversely proportional to the frequency of the wave, so the wavelength will decrease if the frequency of the pulses is increased.
