Problem 32.71

Two identical concave mirrors are set facing each other 1.0 mapart. A small lightbulb is placed halfway between the mirrors. Asmall piece of paper placed just to the left of the bulb preventslight from the bulb from directly shining on the left mirror, butlight reflected from the right mirror still reaches the left mirror.A good image of the bulb appears on the left side of the pieceof paper. What is the focal length of the mirrors?

Chapter 31: Atomic Physics  Line spectrum of hydrogen: a series of individual lines caused by light being emitted by a low­pressure gas when subjected to a large electric field.  Wavelengths in the visible spectrum of hydrogen are given by the following equation: 1 =R 1 − 1 λ (2) n2 where n = 3, 4, 5,… and where R is the Rydberg constant 1.097 x 10^7 m^(­1)   Assumption of Bohr’s Model of the Hydrogen atom: o The electron in a hydrogen atom moves in a circular orbit around the nucleus o Only certain orbits are allowed, where the angular momentum in the nth allowed orbit is nh  L= 2π o Electrons in allowed orbits do not radiate. Radiation is emitted when an ele
