Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index = 1.3; see Figure 1) and 200,000 kilometers per second in glass (refractive index of 1.5).

Answer:

light is a form of wave... I mean not full wave it shows both properties of wave and a particle and I also really get disturbed on thinking about it..

Explanation:

it can penetrate through different medium and it's speed is max in air or vaccum they don't need any medium to travel as there was before myth that there is a substance called ether through which light travels but after in near about 1930 it has proven wrong as it don't need a medium to travel

as it's speed is 3×10^8 m/s....
