Answer the following questions The observations made by swarali while doing the experiment are given below. Based on these write answers to the questions: Swarali found that the light ray trvelling from the denser medium to a rarer medium goes away from the normal. If the angle of incidence (i) is raised by Swarali, the angle of refraction (r) went on increasing . However after certain value of the angle of incidence. the light ray is seen to return back into the denser medium What is the process of reflection of incident ray into a denser medium called ?
