- What are the frequency of and energy of blue light that has wavelength, λ, of 400.0 nm?
- What are the wavelength, λ, and the energy of light that has a frequency of 1.50 X 1015 S-1?
- Determine the energy and wavelength of light associated with an electron moving from the second (n = 2) to the fourth (n = 4) energy level in a hydrogen atom.
