![]() Having clarity on the two properties of light is crucial to gain a stronghold on the advanced concepts. Out of them, the experiment for refraction through glass slab is the most vital.īefore delving deeper into this experiment and its conclusions, students should have prior knowledge of its concept. In this chapter, you are going to study in detail about these two properties with the help of specific situations and conditions. To know more about the refraction of light through a rectangular glass slab, refer to our online study program. ![]() Retrieved 13 March 2021, from 74brch9sim37cnt2.įunded by MeitY (Ministry of Electronics Information Technology). Now, with a protractor, measure angle AEN1, angle FEN2 and angle DFN2 labelled as angle i, angle r and angle e respectively. Thus for the incident ray represented by line AE, the refracted ray and the emergant ray are represented by EF and FD respectively. Closing your one eye,adjust the position of your head in such a way that the images of the pins A and B lie in the same straight line.Įnsure that the feet of the pins ( not their heads ) lie in the same straight line.
