Why the light speeds up while passing from water or glass to air?

$\huge\orange{《ANSWER》}$

Electromagnetic waves simply travel slower through glass than through air. So the wave crests are closer to each other, but the light still oscillates the same number of times per second. It stays the same color.So whenever it's traveling, it's traveling at the speed of light.

$\red{★In Detail}$

If you shine a beam of light (a bundle of parallel rays) through the air, it will travel in a straight line. Rays of light usually travel in straight lines until they hit

When a ray passes from air into glass the direction in which the light ray is travelling changes. The light ray appears to bend as it as it passes through the surface of the glass.
