the speed of light in glass of refractive index 1.5 is 2×10 ^8ms‐1.in a certain liquid the speed of light is 2.5×10^8ms^-1.the reflective index of liquid
Answers
Answer:
The velocity of light in glass whose refractive index with respect to air is 1.5 is 2×108 ms−1. In a certain liquid the velocity of light is found to ...
Top answer
Explanation:
Top answer
Using shell's law sin isin r = v1v2 = μ2μ1 μ 4 = v1v2 1.5 = v12 × 108 v1 = 3 × 108m/s in air Now again μ 21 = 3 × 1082 × 108 μ 21 = 1.5 More
