Question 1 1 pts The sketch shows a concave lens and an object on its optical axis. Where will the position of image be {in cm with correct sign) if the object is 22 cm from the center of the lens and the focal length of the lens is 13 cm? Object Lens Question 3 1 pts You are looking at a calm water surface by standing on a side of a lake. If you want to see only polarized lights entering your eyes, at what should be the incident angle of the rays arriving to the lake surface? Assume refractive index of air is 1.0 and refractive index of water is 1.48 Question 5 1 pts The sketch shows a ray of light refracted on air-water boundary. What is the value of 91 if 62 = 29 ? Assume refractive index of air is 1.0 and refractive index of water is 1.35. m refracted Incident ray 91: ray Medium 1 : air Normal to bounda Medium 2: water I62 Medium 1 : air
