Write a relation for the angle of deviation (δ) for a ray of light passing through an equilateral prism in terms of the angle of incidence (i1) angle of emergence (i2) and angle of the prism (A).
A ray of light incident at an angle of incidence i1 passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges at an angle of emergence i2.
- How is the angle of emergence ‘i2’ related to the angle of incidence ‘i1’.
- What can you say about the angle of deviation in such a situation?
Which of the two prism, A made of crown glass and B made of flint glass, deviates a ray of light more?
A ray of light is normally incident on one face of an equilateral glass prism. Answer the following:
What will be the angle of incidence at the second face of the prism?
A ray of light suffers refraction through an equilateral prism. The deviation produced by the prism does not depend on the ______.
A ray of light incident at an angle of incidence 48° on a prism of refracting angle 60° suffers minimum deviation. Calculate the angle of minimum deviation.
[Hint: δmin = 2i - A]
The angle between two plane rectangular refracting surfaces of a prism is called as
The diagram below shows the path of a blue ray through the prism:
- Calculate the critical angle of the material of the prism for blue colour.
- What is the measure of the angle of this prism (A)?
- Which colour should replace the blue ray, for the ray to undergo Total Internal Reflection?
White light is dispersed by a prism. Inside the prism, compared to the blue light, the red light ______.
