Narendra Kumar Solutions for Chapter: Light - Reflection and Refraction, Exercise 10: PRACTICAL SKILLS BASED QUESTIONS

A student traces the path of a ray of light passing through a rectangular glass slab. For measuring the angle of incidence, which position of the protractor is likely to be correct and why?

In an experiment to trace the path of a ray of light passing through a glass slab, four students $A, B, C$ and $D$ used the following values of angle of incidence and the distance between the feet of two pins (fixed on the incident ray).

Out of these, which is the best choice and why?
