Q2 of 61 Page 65

When a ray of light passes from air into glass, is the angle of refraction greater than or less than the angle of incidence?


As clearly shown in the above when the ray of light from air is going into glass it will deviated from its path .as we known glass is denser then air, so according to the laws of refraction when light is travels from less dense medium to more dense medium it will bend towards the normal , that is the reason the angle of refraction become less then the angle of incident .


So , angle of refraction (r) < angle of incident(i)
