A.A small spotlight mounted in the bottom of a swimming poolthat is 2.5 m deep emits light in all directions. On the surface ofthe pool, directly above the light, the area illuminated is acircle. Determine the maximum radius of this circle. The index ofrefraction of water is 1.33.
B.The index of refraction for blue light ofwavelength 472 nm in a glass sampleis 1.700 and for red light ofwavelength 700 nm it is 1.645. If a beamcontaining these two colors has an angle of incidence with theglass of 30.0°, what is the angle between the two beamsinside the glass?
C.Light travels from air into a glass block with an angle ofincidence in air of 36.0°. The block is then submerged ina liquid and the light now travels from air, through the liquid andinto the glass. When the angle of incidence in the liquidis 20.0°, the angle of refraction in the glass is thesame as when the light entered the glass from air. Determine theindex of refraction of the liquid.
D.A mirror hangs 1.69 m above the floor on a verticalwall. A ray of sunlight, reflected off the mirror, forms a spot onthe floor 1.13 m from the wall. Later in the day, thespot has moved to a point 2.50 m from the wall.
-What is the change in the angle of elevation of the Sun,between the two observations?
