Lab 4 Bending Light (02)

Data Table 1: Measure Index of Refraction n and Speed of Light in this Medium. Keep incident angle θ 1 = 45 o . Vary incident wavelength λ 1 (nm). Measure/record refracted angle θ 2 ( o ) and index of refraction n 2M in medium of glass. Calculate n 2 by Snell’s law: n 2 = n 1 sinθ 1 /sinθ 2 . Calculate speed of light in glass by ʋ 2 = c / n 2 (in unit of c), c is speed of light in vacuum: c = 3.0 x10 8 m/s. Attach screenshots of each Simulation data to Lab Report . λ 1 (nm) θ 2 ( o ) n 2M n 2 = n 1 sinθ 1 /sinθ 2 ʋ 2 = c / n 2 (c) 700 28.2 1.499 1.496 0.668 600 500 400 Questions: • From data λ 1 = 700 nm in air, find the wavelength λ 2 and speed ʋ 2 in 2 nd medium . • Calculate frequency in air and glass for λ 1 = 700 nm. • When the incident λ 1 is changed, what quantities will change in 2 nd medium?

Part C Discovery Beyond what you have done with Bending Light/More Tools Simulation, make few new findings such changing medium, or give real life examples for bending light. You can express your findings by data table, word, equations, and/or screenshot graph/Video, but do giving physics explanation. You could also design meaningful experiments and show them here. In Part C minimum 10 sentences are required.
