(2) While drinking some boba tea, you want to stab a tapioca ball at the bottom of yourtea with your straw. The tea is 9.53cm deep and your eyes are currently 27.6cm above thebottom of your glass (ng = 1.417). As you look at the tapioca ball, your gaze is 81.1° belowthe horizontal and does not look through the side of the glass. We can assume that bobatea and water have the same index of refraction (nw = 1.33).(a) At what angle below horizontal should you insert your straw in order to hit thetapioca ball?(b) A ray of light travels from the air into the tea at an angle of 26.8°. It travels to thebottom where it passes from the tea to the glass. At what angle does the light make afterentering the glass?(c) The light from part (b) continues through the glass and exits back into the air. Whatangle does the light make when it exits to the air?(d) What is the critical angle between the glass and the tea?

The crystalline lens of the human eye is a double-convex lens made of material having an index of refraction of 1.44 (although this varies). Its focal length in air is about 8.00 mm, which also varies. We shall assume that the radil of curvature of its two surfaces have the same magnitude. (Note: The results obtained in the parts A, B and C are not strictly accurate, because the lens is embedded in fluids having refractive indexes different from that of air.)
