The radiation travels at the speed of light. It also provides for the proper units. Thus, use the speed of light:
#c/lambda = nu#
#c# is the speed of light in something-meters per second,#lambda# is wavelength in something-meters, and#nu# is frequency in#"s"^(-1)# .
Therefore:
#=> lambda = c/nu#
#= (2.998 xx 10^(8) "m/s")/(5.11 xx 10^11 "s"^(-1)) = ?#
