60.0x#10^-6# (3 s.f.)

Explanation:

The formula relating velocity, frequency and wavelength is #v=flambda#. Rearranging to find wavelength (#lambda#), we get #lambda=v/f#. The velocity of an electromagnetic wave is the speed of light, approx. 3.00x#10^6#:

#lambda=(3.00*10^6)/(5.00*10^12)=60.0*10^-6#

This is Infra-Red radiation, as you can find by googling the electromagnetic spectrum.
