Consider an RLC circuit with , and .(a)At what frequency is this circuit in resonance? (b) Find the impedance of this circuit if the frequency has the value found in part (a), but the capacitance is increased to . (c) What is the power factor for the situation described in part (b)?

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
