A communications satellite transmits a radio wave at a frequency of 5 • 109 Hz. What is the signal’s wavelength? Assume the wave travels in a vacuum. Show your work

Thank You!

wavelength (m) = speed (m/s) / frequency (1/s)

wavelength = 3*10^8m/s / 5*10^9/s
= .6 * 10^-1 = .06m = 6cm

Thank you so much! :]
