Phys 375 HW 4 Fall 2010 Due 18 October, 2010 1. Consider the disturbance given by the expression ( ) [ ] ) sin( 2 / cos ˆ ) cos( ˆ ) , ( 0 kz E t j t i t z E π ω + = , where i ˆ and j ˆ are unit vectors in the x- and y-directions. What kind of wave is it? Draw a sketch showing its main features. 2. Substances such as sugar, Karo syrup, and insulin are optically active; they rotate the plane of polarization in proportion to both the path length and the concentration of the solution. A glass vessel is placed between two perfect crossed linear polarizers, and 50% of the natural light incident on the first polarizer is transmitted through the second

Unformatted text preview: polarizer. By how much did the sugar solution in the cell rotate the light that passed by the first polarizer? 3. Pedrotti 3 , 3 rd edition, problem 15-1 4. Pedrotti 3 , 3 rd edition, problem 15-2 5. An ideal polarizer is rotated at a rate between a similar pair of stationary crossed polarizers. Show that the emergent flux density will be modulated at four times the rotational frequency. In other words, show that )) 4 cos( 1 ( 8 1 t I I = , where 1 I is the flux density emerging from the first polarizer and I is the final flux density. 6. Pedrotti 3 , 3 rd edition, problem 14-2...
