Define the term dispersion of white light.
As light rays pass from air into a glass prism, are they refracted towards or away from the normal?
In the figure given alongside, a narrow beam of white light is shown to pass through a triangular glass prism. After passing through the prism, it produces a spectrum YX on the screen.
Why do different colours of white light bend through different angles with respect to the incident beam of light?
A beam of white light is shone onto a glass prism. The light cannot be:
(a) deviated
(b) dispersed
(c) focused
(d) refracted
Why do you not see a spectrum of colours when light passes through a flat pane of glass?
