speed of light = wavelength x frequency

speed of light = 2m x 500 Hz

speed of light = 1000 m/s

The wavelength, λ tells us how long one segment of the wave is. The frequency, f tells us how often one whole segment goes by. So the speed is the wavelength (in meters), times the frequency (in Hz)
v=λ f=1000m/s
