What will happen to ray of light when it travels from rarer medium to denser medium? |
|
Answer» It bends towards the normal When the light ray travels from rarer medium to denser medium the light ray get refracted and mov closer to the normal When the ray of light travels from rarer medium to denser medium ,it bends towards the normal Laws of refraction;-\xa0\tThe incident ray,the refracted ray and the normal to the refracting surface at the point of incidence lie in the same plane.\tFor a given pair of media and for a given colour of light the ration between the sine of angle of incidence to the sine of refraction is a constant.This constant is known as refractive index of the second medium with\xa0respect to the first medium.When a ray of light passes through a glass slab,\xa0∠i,∠r\xa0and the normal all lie in the same plane.When a ray of light passes from one medium to another, here from air to glass or glass to air, the ratio\xa0sini\u200b/sinr =constant. |
