Given Solution: `aBrewster's angle is the smallest angle theta_p of incidence at which light is completely polarized.This occurs when tan(theta_p) = n2 / n1, where n2 is the index of refraction on the 'other side' of the interface. For an air-glass interface, n1 = 1 so tan( theta_p) = n2 / 1 = n2, the index of refraction of the glass.We get tan(theta_p) = 1.52 so that theta_p = arcTan(1.52).This is calculated as the inverse tangent of 1.52, using the 2d function-tan combination on a calculator.WE obtain theta_p = 56.7 degrees, approximately. &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Self-critique (if necessary): Ok ------------------------------------------------ Self-critique Rating: Ok ********************************************* Question:`qgen phy problem 24.44foil separates one end of two stacked glass plates; 28 lines observed for normal 670 nm light gen phy what is the thickness of the foil?

Given Solution: `aSTUDENT SOLUTION:To solve this problem, I refer to fig. 24-31 in the text book as the problem stated.Todetermine the thickness of the foil, I considered the foil to be an air gap.I am not sure that this is correct.Therefore, I used the equation 2t=m'lambda, m=(0,1,2,...).THis is where the dark bands occur . lambda is given in the problem as 670nm and m=27, because between 28 dark lines, there are 27 intervals. Solve for t(thickness): t=1/2(27)(670nm) =9.05 *10^3nm=9.05 um INSTRUCTOR RESPONSE WITH DIRECT-REASONING SOLUTION:** Your solution looks good.Direct reasoning: ** each half-wavelength of separation causes a dark band so there are 27 such intervals, therefore 27 half-wavelengths and the thickness is 27 * 1/2 * 670 nm = 9000 nm (approx) ** ****gen phy how many wavelengths comprise the thickness of the foil? GOOD STUDENT SOLUTION:To calculate the number of wavelengths that comprise the thickness of the foil, I use the same equation as above 2t=m'lambda and solve for m. 2(9.05 um)=m(6.70 *10^-7m) Convert all units to meters. m=27 wavelengths. &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& Self-critique (if necessary): ------------------------------------------------ Self-critique Rating: " Self-critique (if necessary): ------------------------------------------------ Self-critique rating: " Self-critique (if necessary): ------------------------------------------------ Self-critique rating: #*&!
