Physics 30: Module 7 17 Assignment Booklet S USE ONLY (3 marks) A 7. What is the shortest wavelength photon that is emitted in the hydrogen atom? What transition emits this photon? Hint: If the wavelength is small, then the energy is large. Looking at the energy level diagram will also help you. A 8. Bohr's model of the atom explains why emission and absorption lines match up. (3 marks) Prove this for the hydrogen atom. Choose any transition (and its opposite) and calculate the wavelength of the emitted and absorbed photon. Verify your answer using the applet
