A beam of white light is directed at a glass prism, where it splits into its component colours, with red and violet light emerging as shown in the diagram.
Which statement correctly describes the light in the prism?
Red light has a shorter wavelength than violet light in glass.
Violet light slows down more than red light when entering the glass.
The frequency of violet light changes more than that of red light when entering the glass.
Red light is refracted more than violet light because it travels faster in glass.
