TOTAL INTERNAL REFLECTION

When a ray of light travels from an optically denser medium to a rarer medium, the refracted ray is bent away from the normal e.g the incident ray ‘AO1’ is partially reflected (O1C) and partially refracted (O1B), the angle of refraction being larger than the angle of incidence. As the angle of incidence increases, the […]

EFFECTS OF TOTAL INTERNAL REFLECTION

(a) Mirage: It is an optical illusion which occurs due to the phenomenon of total internal reflection. When we are travelling on a road on a hot summer day, the road at a distance appears to be covered with water but when we approach the region, we find that there is no water. This phenomenon […]
