Question
Refraction of light takes place because of the _____ that light encounters on passing from one medium to another.
- Change in its speed
- Change in the optical density
- Change in refractive index
- All of the above
Hint:
Change in speed of the light, change in the optical density, and the refractive index causes the refraction of light.
The correct answer is: All of the above
Refraction of light takes place because of the change in speed of the light, change in the optical density, and the refractive index that light encounters on passing from one medium to another. i.e. All of the above
- The refraction in a pair of mediums depends on the speed of light and the density of the medium.
- The optically denser medium refracts the light slower.
- When the light enters a denser medium from a rarer medium, the speed of light changes.
- The refractive index is the ratio of the speed of light in mediums one and two that depends on the density of the medium.
