GIVEN: A monochromatic laser is exciting hydrogen atoms from the n=2 state to the n=5 state.

Question

A: What is the wavelength of the laser?
*435 nm

B: Eventually, all of the excited hydrogen atoms will emit photons until they fall back to the ground state. How many different wavelengths can be observed in this process?
*10

C: What is the longest wavelength that is observed?
* ?? nm
-I know that it occurs from n=4 to n=3, but I'm not sure how to put it into the equation

D: What is the shortest wavelength observed?
* ?? nm

Answer 1

I know C is 4059 nm

Answer 2

D is 95.1nm
