Question:
Consider following statements for refraction of light through prism, when angle of deviation is minimum.
Consider following statements for refraction of light through prism, when angle of deviation is minimum.
Show Hint
Remember the conditions for minimum deviation in a prism. The refracted ray becomes parallel to the base, and the angle of incidence equals the angle of emergence.

- The refracted ray inside prism becomes parallel to the base.
- Larger angle prisms provide smaller angle of minimum deviation.
- Angle of incidence and angle of emergence becomes equal.
- There are always two sets of angle of incidence for which deviation will be same except at minimum deviation setting.

The Correct Option is A
Solution and Explanation
\( \delta = I + e - A \) For \( \delta_{min} \)
\(\Rightarrow I = e \) and refracted ray is parallel to base A, C, D are correct

- Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : If Young’s double slit experiment is performed in an optically denser medium than air, then the consecutive fringes come closer.
Reason (R) : The speed of light reduces in an optically denser medium than air while its frequency does not change.
In the light of the above statements, choose the most appropriate answer from the options given below : - A plane wave travelling in a medium is incident on a plane surface separating this medium from a rarer medium. Draw a diagram to show refraction of the wave. Hence, verify Snell’s law.
