The wavelength of a wave on a string is 1.2 meters. if the speed of the wave is 60 meters/second, what is its frequency? a. 0.20 hertz b. 2.0 hertz c. 50 hertz d. 10 hertz e. 15 hertz

C. 50Hz. The wavelength of a wave on a string is 1.2m with a speed of 60m/s its frecueny is 50Hz.

The wavelength of a wave describes how long the wave is, and can be represented by the formula λ = v/f, where λ is the wavelenght in meters, v is the speed of the wave in m/s, and f is the frecuency of the wave in Hertz.

The wavelength of a wave on a string is 1.2m and its speed is 60m/s, to calculate its frecuency we have to clear f from the equation λ = v/f. So:

f = v/λ

f = (60m/s)/(1.2m)

f = 50 1/s = 50Hz
