Refractive Index

Glass and gly...

Question

Glass and glycerin have the same refractive index. How will you observe the reflection and refraction phenomenon in a glass-glycerin interface?

Open in App

Solution

There is no refraction at glass-glycerine interface as the refractive index is same. Refraction is due to speed of light is different from one medium to another one. If in two mediums, speed of light is same, there's no refraction. There's no change in the direction of light when light passes from glycerine to glass & goes out from glass to glycerine.
