Question

If a ray of light is incident at same angle on three different media A,B and C. And the angle of refraction is 18°,25° and 30° respectively.From which of these will have maximum density

Answer 1

According to the first law of refraction, when light changes medium from rarer to denser medium, the light ray bends towards the normal. The amount of bending increases with the increase in density.

So, if the angle of refraction were to decrease, it means that the density of the medium is high.

So Medium A is of greater density as it jas the least angle of refraction of the three.

Answer 2

Explanation:

A have maximum density compare to C and B
