A wave with a wavelength 0.68 m travels a distance of 850m in 2.5 seconds. What is the frequency of the wave

Frequency of wave = 500 Hz

Explanation:

Given

Wavelength = 0.68 m

Distance = 850 m

Time = 2.5 s

Frequency = ?

In order to find frequency, we have to calculate velocity. We know that the velocity is given by formula:

          velocity =

                        = 850 m / 2.5 s

                        = 340 m

Also we know that for all waves, the relationship between wavelength λ, frequency f and velocity v is same and given by the equation:

                                              v = fλ

Hence frequency f = v/λ

                               = 340 m / 0.68 m

                               = 500

                               = 500 Hz
