Why do different components of white light deviate through different angles when passing through a prism ?

For refractin of light through a prism

In the above figure a narrow beam of white light is shown to pass through a triangular glass prism. After passing through the prism, it produces a spectrum XY on a screen. State the colour seen at (i) X and (ii) Y.

Out of the following, which light is deviated minimum in the dispersion of white light through a glass prism?

Give the relationship between wavelength of light and its angle of deviation, when it is passed through a prism.

State the causes of dispersion of white light as it passes through a triangular glass prism.

Why do we get different colours in the phenomenon of dispersion of white light through prism?

When no current is passed through a conductor,

Which colour of light deviates maximum in the dispersion of white light by a prism?
