What happens when light enters glass from air? When a ray passes from air into glass the direction in which the light ray is travelling changes. … This ‘bending of a ray of light’ when it passes from one substance into another substance is called refraction. The bending of a ray of light also occurs when the ray comes out of glass or water and passes into air.
What happens when light goes from air into glass? Glass is denser than air, so a light ray passing from air into glass slows down. … A light ray speeds up as it passes from glass into air, and bends away from the normal by the same angle. A useful way of remembering the speed and direction changes of light during refraction is ‘FAST’: Faster – Away / Slower – Towards.
What will happen when light enters the glass which is denser than air? If light enters any substance with a higher refractive index (such as from air into glass) it slows down. The light bends towards the normal line.
