The angle of incidence and the angle of refraction. Find the index of refraction

Question

The angle of incidence and the angle of refraction. Find the index of refraction of the plastic disk. c) Repeat a) and b) for another angle about 60 degree. Parallel plate a) Place a parallel plate on a piece of paper so that the angle of incidence is about 40 degree (Figure 5). Trace the outline of the parallel plate. Mark two points each on the incident ray to the plate and the outgoing ray from the plate. b) Draw the incident ray, the refracted ray inside the plate, and final outgoing ray. Draw the normal for each of the boundary surfaces. Measure the angle of incidence and the angle of refraction for each surface. Find the index of refraction of the parallel plate from the refraction from each surface and calculate the average. c) What is the relationship between the initial incident ray and the final outgoing ray? Are they parallel? What factors does the distance between these two lines depend on (See also Question 1)? "Convex Lens" a) Place the "convex lens" on a piece of paper so that the incoming light beam hits the center of the lens and the angle of incidence is 0 degree (The incident ray is perpendicular to the surface of the convex lens at that point.) Trace the front and back surface of the lens. Mark two points that are as far apart as possible on the incident ray. Where is the refracted ray? b) Slide the platform to one side from the center by about 1.0 cm to get a parallel incident ray.

Explanation / Answer

Apart from c all the questions are experiments.
However,

c) the incident and final refractive rays are parallel to each other. The distance between them depends on the refractive index of the glass and the separation between the two faces of it.
