(a) ∠A and ∠i
(b) ∠A, ∠i and ∠r
(c) ∠A, ∠i, ∠e and ∠D
(d) ∠A, ∠i, ∠r and ∠D
As light rays pass from air into a glass prism, are they refracted towards or away from the normal?
Make two diagrams to explain refraction and dispersion.
What is a rainbow?
The splitting of white light into its constituent colours is called .............
In figure AO is the ray of white light falling on a prism PQR. Complete the diagram till the light emerges out from the prism and falls on the screen.
Explain the cause of dispersion of white light through a prism.
Explain briefly, with the help of a neat labelled diagram, how white light gets dispersed by a prism. On which surface of a prism, there is both dispersion and deviation of light, and on which surface of the prism, there is only deviation of light ?
When white light enters a glass prism from the air, the angle of deviation is least for ____________.
______ colour is deviated the least in the spectrum of white light obtained with a glass prism.
