What is the speed of a periodic wave disturbance that has a frequency of 3.50hz and a wavelength of 0.700m?

The speed of a periodic wave disturbance is 2.45 m/s.

Explanation:

Sound waves travel as sinusoidal nature. And the distance between the two successive crests or troughs are determined as the wavelength of the sound wave.

Similarly, the measure of number of complete cycles in a given time is defined as frequency of sound wave. The speed of any wave is determined as the product of wavelength of transmission of wave and frequency of that wave.

Thus,

×

So,

× = 2.45 m/s.

Thus, the speed of periodic wave disturbance is 2.45 m/s.
