Question
A:
A thin hemispherical bowl of clear plastic floats on water in a tank. The radius of the bowl is 50 cm and the depth of the bowl in water is 10 cm. The depth of the water (n = 1.33) in the tank is h = 200 cm. An object 8.0 cm long is on the bottom of the tank directly below the bowl. The object is viewed from directly above the bowl. Ignore the refractive effects of the plastic. In the figure, the position of the image below the water level, in cm, is closest to:
B:
A double convex thin glass lens has equal radii of curvature. The focal length of the lens is +62.7 cm and the index of refraction of the glass is 1.52. The lens is replaced with a plano-convex glass lens of the same focal length and thickness. The radius of curvature of the convex surface is 13.0 cm. The index of refraction of the glass of the plano-convex lens is closest to:
