The distance between two successive crests of a wave is 15cm and the velocity 300ms-1. Calculate the frequency.
Answer Details
The formula to calculate frequency is: frequency = velocity / wavelength where wavelength is the distance between two successive crests of a wave. In this problem, the wavelength is given as 15cm or 0.15m, and the velocity is given as 300ms^-1. Substituting these values in the formula, we get: frequency = 300 / 0.15 = 2000 Hz Therefore, the frequency of the wave is 2.0x10^3 Hz. Answer: 2.0x103Hz
