60.0x $10^{- 6}$ $10^-6$ (3 s.f.)

Explanation:

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

$λ = \frac{3.00 \cdot 10^{6}}{5.00 \cdot 10^{12}} = 60.0 \cdot 10^{- 6}$ $lambda=(3.00*10^6)/(5.00*10^12)=60.0*10^-6$

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