प्रश्न
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?

उत्तर
Different colours of white light bend at different angles with respect to the incident beam of light. This is because different colours have different wavelength.
