Which of the prism is used to see infrared spectrum of light
DoubtBuddy
Subjective Type
(a) What happens when a ray of ordinary light is passed through a triangular glass prism? (b) What will happens if another similar glass prism is placed upside down behind the first prism?
Solution
(a) When a ray of ordinary light is passed through a triangular glass prism, it splits to form a band of seven colours.
(b) If another similar glass prism is placed upside down behind the first prism, then the seven coloured rays from the first prism which are incident on the second prism recombine to form the original white beam.
