The deviation produced by a prism is independent of the angle of incidence and is same for all the colours of light.
Diagrams (a) and (b) in figure below show the refraction of a ray of light of single colour through a prism and a parallel sided glass slab respectively.
- In each diagram, label the incident, refracted, emergent rays and the angle of deviation.
- In what way the direction of emergent ray in the two cases differ with respect to the incident ray? Explain your answer.
How does the angle of deviation depend on the refracting angle 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?
A ray of light suffers refraction through an equilateral prism. The deviation produced by the prism does not depend on the ______.
When white light enters a prism, it gets split into its constituent colours. This is due to:
Assertion: When a pencil is partly immersed in water and held obliquely to the surface, the pencil appears to bend at the water surface.
Reason: The apparent bending of the pencil is due to the refraction of light when it passes from water to air.
The diagram below shows the ray OP travelling through an equilateral prism of a certain material.
- Calculate the value of i2, if the angle of deviation is 43°.
- What is the ray QS called?
Name the colour of white light which is deviated the least on passing through a prism.
