The speed of light is the fastest speed at which information or energy can travel through a vacuum. It is 299,792,458 meters per second. The speed of light in a vacuum is the same for all observers, regardless of their motion relative to the light source.
The speed of light in a medium, such as water or glass, is slower than the speed of light in a vacuum. This is because the light waves interact with the atoms and molecules in the medium. The amount of interaction depends on the properties of the medium, such as its density and refractive index.
The refractive index of a medium is a measure of how much light is slowed down by the medium. The refractive index of water
is 1.33, and the refractive index of glass is 1.52. This means that light travels 1.33 times slower in water than in a vacuum, and 1.52 times slower in glass than in a vacuum.The speed of light is minimum in a vacuum. This is because
there is no interaction between the light waves and the vacuum. The speed of light is maximum in a vacuum, and it is slower in all other media.The correct answer to the question “The speed of light will be minimum while passing through” is:
- B. Vaccum
The speed of light is minimum in a vacuum. This is because there is no interaction between the light waves and the vacuum. The speed of light is maximum in a vacuum, and it is slower in all other media.
