A light ray strikes a water/unknown surface at an angle of D degrees with respect to the normal. Find the angle of refraction when the direction of the ray is from water to unknown media. The refractive index of water is 1.33 and for the unknown is C/ 100. (20 points) . An object is placed D cm from a B cm focal length converging lens. Determine the image position, size and orientation? a) analytically b) Using ray diagram. (20points) . An object is placed D/2 cm from a B cm focal length concave mirror.

A beam oflight travelling through water (n=1.33) strikes a piece of glass (n=1.5) at an incident angle 9 as shown in the Figure. What is the minimum angle 9 (in degrees) such that the light will not reach the air (n=1) on the other side ofthe glass? \"'nler n] = 1.33 ' Glass n2 =1. An object B/ 10 cm tall is located D/5 cm in front of a mirror. If the mirror produces a 3 cmtall upright image what kind of mirror is this and what is the magnitude of its radius of curvature? 6. An object placed in front of a spherical mirror with focal length f = B cm produces an image with a magnification m: D/ 10. If the object is placed the same distance in front of a spherical mirror with focal length f = B cm, what Dr. Hetti l PHY 156
