Calculate the refractive index of the material of the glass block shown in the diagram if YZ = 4cm?
A. 0.40 B. 0.60 C. 1.50 D. 1.67 E. 2.50 Correct Answer: Option D – 1.67 Explanation n = real depth/apparent depth 10/10^−4 = 1.6A ray of light is incident at an angle of 30°on a glass prism of refractive index 1.5. Calculate the angle through which the ray is minimally deviated in the prism. (The medium surrounding the prism is air)
A. 10.5° B. 19.5° C. 21.1° D. 38.9° E. 40.5° Correct Answer: Option A – 10.5° Explanation n = sin i/sin r sin r = 30°/n sin r = 0.51.5 sin r = 0.3333 r = 19.5°; Deviation 30 – 19.5 =...
