What would the wavelength of radiation whose frequency is 5.75*10 to the 9th cycles per second be?

Name the type of radiation it is?

c = frequency*wavelength
how do i find the wavelength?
You plug in the frequency value from the problem, c (the speed of light), and solve for wavelength.
Do you know the speed of light? It is a constant; 3 x 10^8 m/s.
