An electron relaxed to a lower energy level and emitted a photon with a wavelength of 472.5nm. What was the energy difference between the excited state level and the ground state? what was the frequency of this photon?

(a) A green laser pointer emits light with a wavelength of
532 nm. What is the frequency of this light? (b) What is the energy of one of these photons? (c) The laser pointer emits light because electrons in the material are excited (by a battery) from their ground state to an upper excited state. When the electrons return to the ground state, they lose the excess energy in the form of 532-nm photons. What is the energy gap between the ground state and excited state in the laser material?

c) The energy gap between ground state and excited state corresponds to the energy of the light emitted. As wavelength of emitted photons is 532 nm, energy gap is:

The electron in an (unbound) hydrogen atom (H(g)) is excited from the ground state to the n=3 state. Which of the following statements are true and which are false.

The wavelength of light emitted when the electron drops from n=3 to n=2 is longer than the wavelength of light emitted if the electron falls from n=3 to n=1.

The wavelength of the light emitted when the electron returns to the ground state from n=3 is the same as the wavelength of light absorbed to go from n=1 to n=3.

The electron is farther from the nucleus on average in the n=3 state than in the ground state.

It takes more energy to ionize the electron from n=3 than it does from the ground state.

The first excited state corresponds to n=2.
