Detailed Solution

The above statement is true.
We know that the wavelength of the colour is inversely proportional to its deviation angle as all colours have different wavelengths. Hence, different colours of light bend through different angles with respect to the incident ray after they pass through a prism. The red colour has the highest wavelength, so it bends at least an angle. On the other hand, violet has the lowest wavelength of the seven colours, so it bends the most.
