Question

A ground state hydrogen atom absorbs a photon of light having a wavelength of 93.03 nm. It then gives off a photon having a wavelength of 396.9 nm. What is the final state of the hydrogen atom? Values for physical constants can be found here.

Answer 1

Now I just did one using the same relationships between frequency, period, speed of light, wavelength and energy. This one is the same.

Answer 3

note,
absorbed high energy
radiated much lower energy
therefore, energy of atom went up.
