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.
- State the colour seen
- at X, and
- at Y.
- Why do different colours of white light bend through different angles with respect to the incident beam of light?
Make two diagrams to explain refraction and dispersion.
What acts as tiny prisms in the formation of a rainbow?

Out of air and glass, which is optically rarer? Give reason.
In an experiment to trace the path of a ray of light through a triangular glass prism, a student would observe that the emergent ray
(a) is parallel to the incident ray.
(b) is along the same direction of incident ray.
(c) gets deviated and bends towards the thinner part of the prism.
(d) gets deviated and bends towards the thicker part (base) of the prism.
Draw a labeled ray diagram to illustrate the dispersion of a narrow beam of white light when it passes through a glass prism.
