Question

yellow light emitted from a sodium lamp has a wavelength (lemda) of 580 nm. calculate the frequency (v) and wavenumber of the yellow light​

Answer 1

Answer:

So if the question asked for the frequency and you have 580 nm you would set it up like this: (2.99792 x 10^8 m/s)/(5.8 x 10^-7 m) = 5.2 x 10^14 m
