(a) Draw the ray diagram for refraction of light through a glass prism and mark angle of refraction and angle of deviation.
(b) When the path of a light ray refracted through a glass prism is reversed how will the angle of deviation change ? Explain.
Solution
(a)
Diagram
Labelling ½+½
(b)
• Angle of deviation will not change.
• The ray of light will retrace its original path.
