boomerang285

f=c/wavelength. Please help, not sure how to calculate f. c= 3.00 x 10^8 m/s wavelength = 268nm

    you did not concert the wavelength which is on nanometers into meters..

    no..... nano = 1* 10^-9

    I 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?

    to convert the wavelength from nanometers to meters you need to multiply by 10^-9

    nano in its number state is 10^-9.....so nm=10^-9m

    no since nano is 10^-9, it is supposed to be 2.68 x 10^-9m

    oh ok.... makes sense, so then the equation (f=c/wavelength) has those values in it?

    it looks like this though right? 3.00 x 10^8 / 2.68 x 10^-9
