उत्तर
No. The velocity of light is not the same in all media.
- The speed of light depends on the optical density (refractive index) of the medium.
- Light travels fastest in vacuum, slightly slower in air, and slower in denser media such as water and glass.
- The greater the refractive index of a medium, the lower the speed of light in that medium.
Therefore, the velocity of light is different in different media.
