The light beam shown in Figure P22.19 makes an angle of 20.0° with the normal line NN' in the linseed oil. Determine the angles θ and θ'. (The refractive index for linseed oil is 1.48.)
A light beam is directed parallel to the axis of a hollow cylindrical tube. When the tube contains only air, it takes the light 8.72 ns to travel the length of the tube, but when the tube is filled with a transparent jelly, it takes the light 2.04 ns longer to travel its length. What is the refractive index of the jelly?
NOTE: The final answer should be 1.23.
Figure P22.59 shows the path of a beam of light through severallayers with different indices of refraction. (a) If Θ1 = 30.0°,what is the angle Θ2 of the emerging beam? (b) What must
the incident angle Θ1 be to have total internal reflection at thesurface between the medium with n = 1.20 and the mediumwith n = 1.00?
