Question

tracing the path of the rays of light through a glass prism

Answer 1

@im - to trace the lath of rays of light through a glass prism

Procedures-

1) Fix a sheet of a white paper on drawing board using drawing pins

2) Place a glass prism on it in such a way that it rests on its triangular base . Trace the outline of prism using pencil

3) Draw a straight line PE inclined to AB and fix two pins at point P and W on PE

4) Look for the images of pins and fix pins R and S on the straight line made from the images of P And Q

5) Remove the pins and prism

6) Line PE meets boundary of prism at point E and similarly join and produce R and S such that these lines meet the boundary of E and F .
join E and F

7)draw perpendiculars to the refracting surface AB and AC of the prism at points E and F respectively
8) Mark an angle of incidence <i, angle of emergence <e and angle of refraction <r
there is also a angle between the emergent ray and the incident ray called as angle of deviation

~~~~which ic caused by the peculiar shape ( triangular shape) of prism

thus the emergent ray bend away from normal or base of prism as show in figure

hope helped.
