As light rays pass from air into a glass prism, are they refracted towards or away from the normal?
What is spectrum?
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?
Why do you not see a spectrum of colours when light passes through a flat pane of glass?

When white light enters a glass prism from the air, the angle of deviation is least for ____________.
Assertion: We can see the rainbow in the sky when the rain starts falling after a spell of bright sunlight.
Reason: The rainbow is formed due to the dispersion of light.
