Problem 90

Figure 26-79 shows the circuit for a simple sawtooth oscillator.At time t = 0, its switch S is closed. The neon bulb hasinitially infinite resistance until the voltage across it reaches90.0 V, and then it begins to conduct with very little resistance(essentially zero). It stops conducting (its resistance becomesessentially infinite) when the voltage drops down to 65.0 V.(a) At what time t\ does the neon bulb reach 90.0 V and startconducting? (b) At what time t2 does the bulb reach 90.0 Vfor a second time and again become conducting? (c) Sketchthe sawtooth waveform between t = 0 and t = 0.70 s.

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
