What is the frequency of a photon with a wavelength of 2.25 102 nm? (The speed of light in a vacuum is 2.998 108 m/s. Planck's constant is 6.626 10-34 Js

c = fw. c is speed of light which you have, f is frequency for which you must solve, w is wavelength which you have. One unknown. Solve for f.

Post your work if you get stuck. Remember to convert nm to meters.

i did 2.99E8 / 2.25E11 and i got 1.33E-3 but this homework is online and it said the answe is wrong and i have the right right sig figs

225 nm is NOT 2.25E11

nm= 10^-9

225nm= 10^-7 m check my thinking

You should be getting 1.33 x 10^15 hz
