Best ResponseYou've already chosen the best response.0but i get a giant number, and not sure what I do after that.. i need to figure out f=____hz

Best ResponseYou've already chosen the best response.0you did not concert the wavelength which is on nanometers into meters..

Best ResponseYou've already chosen the best response.0I don't get how to plug in the numbers, when I have to change them as well. 268 nm changes to meters right? is it not 268nm= 2.68 x 10^7m?

Best ResponseYou've already chosen the best response.0to convert the wavelength from nanometers to meters you need to multiply by 10^9

Best ResponseYou've already chosen the best response.0nano in its number state is 10^9.....so nm=10^9m

Best ResponseYou've already chosen the best response.0no since nano is 10^9, it is supposed to be 2.68 x 10^9m

Best ResponseYou've already chosen the best response.0oh ok.... makes sense, so then the equation (f=c/wavelength) has those values in it?

Best ResponseYou've already chosen the best response.0yes....so what do you get after you plug in the numbers??

Best ResponseYou've already chosen the best response.0this is the tricky part for me.. I dont know how to correctly work it out

Best ResponseYou've already chosen the best response.0it looks like this though right? 3.00 x 10^8 / 2.68 x 10^9

Best ResponseYou've already chosen the best response.0do you get it now??

Best ResponseYou've already chosen the best response.0yes, so obviously I don't put in all the numbers.. so f = 11.15?
