Question

A wave has a frequency of 4.00 hz and a wavelength of 10.0 m. What is the speed of the wave?

Answer 1

First use this equation to find the wave speed: vms== =τµ/ 0.4/ 0.001 20 / Then use the equation for solving frequency of a wavelength, and solve for wavelength λ = v/f = 20/100 = .2 m = 20 cm.
