Question

a piece of glass when immersed in a transparent solution of refract index 1.55, Become almost invisible . the refractive index of glass is used​

Answer 1

The Refractive index of glass will be the same as the solution.

1. Refraction takes place when light enters from one medium to another medium with a different refractive index.
2. The change in speed of light is responsible for the change in direction of light.
3. When the refractive index of two mediums is the same, the light will not bend.
4. Thus, the light will pass through glass and solution without bending and glass will not be recognised.
