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?
A ray of light is normally incident on one face of an equilateral glass prism. Answer the following:
What is the angle of incidence on the first face of the prism?
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?
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.
A prism ABC (with BC as base) is placed in different orientations. A narrow beam of white light is incident on the prism as shown in below Figure. In which of the following diagrams, after dispersion, the third colour from the top of the spectrum corresponds to the colour of the sky?
Draw a ray diagram showing the dispersion through a prism when a narrow beam of white light is incident on one of its refracting surfaces. Also indicate the order of the colours of the spectrum obtained.
A monochromatic ray of light is incident on an equilateral prism placed at minimum deviation position with an angle of incidence 45° as shown in the diagram?
- Copy the diagram and complete the path of the ray PQ.
- State two factors on which the angle of deviation depends.
Name the colour of white light which is deviated the least on passing through a prism.
