Can someone tell me if I answered this correctly? (My chem book doesn't give the answer despite the fact that it's an example problem)

A lazer dazzles the audience in a rock concert by emitting green light with a wavelength of 515 nm. Calculate the frequency of the light

v=c/lambda

3.00*10^8/515*10^-9

=5.813*10^14 m

I agree with the work.  The number seems a bit off (5.813 when I get 5.825 from those numbers).  The units should be in 1/s or Hz (it is a frequency and not a wavelength, or observe units: m/s / m = 1/s)

Thank you! I actually got that but I rounded to 3 sig figs. 5.83***

Glad to help!  And, that makes more sense then!  :)
