lamda * f = c
where c is the speed of light = 3*10^8 m/s; f is the frequency; lambda is the wavelength.
I have all of the answers but this one so if anyone knows this answer, i can trade you :)
I tried using the formulas that were posted but i ended up with a weird answer that didn't work....
A photon interacts with a ground state electron in a hydrogen atom and is absorbed. The electron is ejected from the atom and exhibits a de Broglie wavelength of 5.908 x10^-10m. Determine the frequency (in hz) of the interacting photon.
