#"Wavespeed"# #=# #"frequency"xx "wavelength"#

Explanation:

So, #nu("frequency")# #=# #"Wavespeed"/"Wavelength"# #=# #c/lambda# #=# #(3xx10^8*cancelms^-1)/(4.06xx10^-11*cancelm)#.

We get an answer in inverse seconds, #s^-1#, which is good because these are precisely the units required for a frequency. The frequency of course will be rather large.
