The formula is f = v/lambda.
Photons with a frequency of 6.45*10^14 Hz are incident on excited atoms, causing the atoms to emit their excess energy.
Calculate the wavelength of the laser light produced. Give your answer to the nearest nanometre
The answer i got was 4.65*10^-7 however, the answer should be .465*10^3
