If refracted light bends towards normal that means light speed has been slower down. We knew that if refracted light bends towards normal that means light is traveling from rarer to denser medium. So let n2 be the refractive index of denser medium and n1 be the refractive index of rarer medium. So ,We know n2>n1 and n=n2/n1 so n will be greater than 1. And v=c/n so speed of light in denser medium will reduced by n times .

(5.) Light propagates from air into a material whose index of refraction is two. At the instant shown, point a is just entering the new material. Point b is on the same wavefront as point a but is still in air. (a.) Using the dashed lines as a guide, determine the location of point a when point b reaches the bounda between the two materials. (b.) Use the new locations of points a and b to draw the wavefront once...

2. Use Snell's law (n, sin = n, sine,) to explain why , is greater than 0 in Fig. 2. Total Internal Reflection When light passes from a medium of large refractive index into one of small refractive index --- for example, from water to air --- the refracted ray bends away from the surface normal, as shown in Fig. 2. As the angle of incidence increases, the angle of refraction also increases. When the angle of incidence reaches a...
