प्रश्न
Images formed by totally reflecting prisms are brighter than the image formed by ordinary reflected light, why?
उत्तर
This is because in total internal reflection 100% of incident light gets reflected. On the other hand, in ordinary reflection, 20% to 30% of incident light is lost. So, images formed in the first case are brighter than the images formed in the second case.

The observation made by Swarali while doing the experiment is given below. Based on these write answers to the questions:
Swarali found that the light ray travelling from the denser medium to 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.
Questions:
- What is the specific value of∠i called?
- What is the process of reflection of incident rays into denser medium called?
- Draw the diagrams of three observations made by Swarali.
