Question

In which medium the speed of light is lesser glass or air

Answer 1

the answer will be glass

Answer 2

In a vacuum, the speed of light remains constant assuming its path does not get interrupted by another medium. This speed, known as C, is equal to - 299,792,458 m / s

Now when light encounters a medium, its phase velocity is altered and it ends up taking a longer path than it would otherwise take (for example in a vacuum). The actual speed is unaltered, but an observer would perceive it taking longer to travel through the medium, hence the assumption that it slows down.

Fermat's principle - Light will always take the shortest path and hence transverse through the medium in the least possible time.

Air is a medium where light will constantly be absorbed, emitted and scattered between the particles in the atmosphere - some colours such as blue are scattered more while other colours such as orange and yellow are scattered less due to the variation in wavelength of particular colours.
