Problem
A monochromatic light of wavelength 550nm in air enters water (refractive index 1.33) and then crown glass (refractive index 1.52) in succession.
(i) Calculate the speed of light in water.
(ii) Determine its wavelength in crown glass.
(iii) Find the ratio of the wavelength in water to that in crown glass.
