Questions
The optical path of monochromatic light is the same if it travels 2 cm thickness of glass or 2.25 cm thickness of water. If the refractive index of water is 1.33, what is the refractive index of glass?
detailed solution
Correct option is B
Optical path = μ × Path in medium.The optical path for glass = Optical path for water.μg = (1.33×2.25)/(2.0)μg = 1.50.Talk to our academic expert!
