According to optics, the medium in which speed of light is more is called rarer medium. Only when the light ray travels along the normal to the surface, it does not change the direction. In all other cases, light bends during refraction. Rarer medium According to optics, the medium in which speed of light is less is called denser medium. Denser medium To understand refraction of light through figures, the following terms are important. At the point of incidence where the light ray strikes the interface between the two media, a line drawn perpendicular to the surface is known as normal. It is labeled as N with the help of dotted line in the figure. NORMAL The angle between the incident light ray and the normal is called angle of incidence. <a href="https://interviewquestions.tuteehub.com/tag/denoted-7335278" style="font-weight:bold;" target="_blank" title="Click to know more about DENOTED">DENOTED</a> by Li ANGLE OF INCIDENCE ( i) The angle between the refracted light ray and the normal is called angle of refraction.
