(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A certain helium-neon laser emits red light in a narrow band of wavelengths centered at 632.8nm and with a wavelength width if .01nm. What is corresponding frequency width for the emission?

2. Relevant equations

f=c/[itex]\lambda[/itex] ?

3. The attempt at a solution

I tried using the above with both numbers given. This is supposed to be an easy problem, but i think theres something im missing here... Answer is 7.49GHz?
