Draw the diagram given below and clearly show the path taken by the emergent ray.
How does the angle of minimum deviation produces by a prism change with increase in :
the refracting angle of prism?
Name the colour of white light which is deviated the most on passing through a prism.
A ray of light falls normally on the surface of a transparent glass slab. Draw a ray diagram to show its path and also mark angle of incidence and angle of emergence.
A ray of light strikes the surface at a rectangular glass slab such that the angle of incidence is 45o.
In each case, draw diagram to show the path taken by the ray as it passes through the glass slab and emerges from it.
How does the deviation produced by a prism depend on the refraction index of its material.
During sunset and sunrise, the sun is seen when it is slightly below the horizon. Give reason.
A ray of light PQ is incident normally on the hypotenuse of a right-angled prism ABC as shown in the diagram given below:
(i) Copy the diagram and complete the path of the ray PQ till it emerges from the prism.
(ii) What is the value of the angle of deviation of the ray?
(iii) Name an instrument where this action of the prism is used.
