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.
Which of the two prism, A made of crown glass and B made of flint glass, deviates a ray of light more?
An object is viewed through a glass prism with its vertex pointing upwards. Draw a ray diagram to show the formation of its image as seen by the observer on the other side of the object.
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 refraction of light through a prism, the light ray ______.
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:
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?
How will you use two identical prisms so that a narrow beam of white light incident on one prism emerges out of the second prism as white light? Draw the diagram.
State three factors on which the angle of deviation depends.
