1. Suppose the figure below represents a ray of light going from air through crown glass into water, such as going into a fish tank. Calculate the amount the ray is displaced by the glass (4x), given that the incident angle is 30 and the glass is 1.1 cm thick. The refractive index of glass is 1.52. n m2 n AX Amount of ray displacement, Ax: v mm
1. A ray of light, emitted beneath the surface of an unknown liquid with air above it, undergoes total internal reflection as shown in the figure. n2 — 13.4 cm n e 15.0 cm (a) Calculate the critical angle from the figure. Critical angle, 8: V 0
(b) What is the index of refraction for the liquid and its likely identification from the table below? Liquids at 20°C Benzene 1.501 Carbon disulfide 1.628 Carbon tetrachloride 1.461 Ethanol 1.361 Glycerine 1.473 Water, fresh 1.333 Most likely compound: Benzene Carbon disulfide O Carbon tetrachloride Ethanol Glycerine Water, fresh
