The speed of light in an organic liquid is 1.92 x 10 ^ 8m/s while its speed in air is 3.00 x 10 ^ 8 m/s Determine the refractive index of the liquid. A 1.0 m long ruler is placed into a container containing the liquid in part (a). The depth of the liquid is 0.35 m. A student is standing a short distance from the container as shown in the diagram. refractive index, n = 1.5625 Angle of refraction, r = 50.8 Angle of incidence, i = 29.7 Calculate the apparent length of the ruler 1-0 m Apparent length 1-35 m 0.35 m Eye 1.45 m
