UAHuntsville PH 113 Spring 2010 Homework Problem Set No. 4 Submission deadline: 3/3/2010 Problem 21: Problem 22: Problem 23: Imagine that some electrons are moving at a speed of 0.001c in a magnetic field that keeps them in circular orbit 20cm in radius. Assume that the electrons are moving in a vacuum. About how much time will elapse before the radius of the orbit of the electrons has decreased to 10cm? Problem 24:

Unformatted text preview: a beam of natural light of intensity I . If the first and last polarizers are crossed and if the middle one rotates at with angular frequency about the axis, write an expression for the intensity of the emerging beam as a function of I , . Notice : simplify your expression so that the frequency of the beams intensity is manifest. Problem 27:...
