Define the term angle of deviation.
A light ray of yellow colour is incident on an equilateral glass prism at an angel of incidence equal to 48° and suffers minimum deviation by an angle of 36°.
- What will be the angle of emergence?
- If the angle of incidence is changes to (a) 30°, (b) 60°, state whether the angle of deviation will be equal to, less than or more than 36°?
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:
Will the light ray suffer minimum deviation by the prism?
In following figure shows two identical prisms A and B placed with their faces parallel to each other. A ray of light of single colour PQ is incident at the face of the prism A. Complete the diagram to show the path of the ray till it emerges out of the prism B.
[Hint: The emergent ray out of the prism B will be parallel to the incident ray PQ]
Draw a ray diagram to show the refraction of a monochromatic ray through a prism when it suffers a minimum deviation. How is the angle of emergence related to the angle of incidence in this position.
What should be the angle of incidence for a ray of light which suffers a minimum deviation of 36° through an equilateral prism?
[Hint: A = 60°, i = (A + δmin)/2]
Explain the phenomenon of dispersion of white light through a glass prism, using suitable ray diagram.
