glass water 1. A concave spherical surface separates water (n = 1.333) and glass (ng = 1.533). Find the image of a point source in the water on the optical axis 1 m from the surface if r = -5 cm. 2. Consider the block of glass (n = 1.5) shown in the figure above. If the point source is 30 cm from the vertex of the hemispherical end whose radius is 10 cm, locate the image seen by the observer. O V, A borosilicate crown glass sphere (n, = 1.56) of radius 6 cm is surrounded by ethyl alcohol (n, = 1.36). An ant drifting in the alcohol is 9 cm from the sphere's center; describe its image. 3.
