Using Kirchhoffs rules, (a) nd the current in each resistor shown in Figure P18.23 and (b) nd the potential difference between points c and f.

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
