Wavelength to Frequency

Postby Marty Hockey » Tue Nov 05, 2019 7:40 pm

Hello, can anyone tell me the steps to go from a given wavelength and work function to frequency?

Convert wavelength to E (joules) using E=hc/λ
Plug E into E=hν, solve for v (frequency in Hz)

Sorry I should have clarified, this is for an electron not light.

For an e-, you can find the wavelength by using the de Broglie's equation lambda = planck's constant/momentum. You can't find the frequency of an e-.
