Question

The given diagrams show the splitting up of a composite light into its constituent colours.


Which among the given figures is correct?

• A. (i)
• B. (ii)
• C. (iii)
• D. (iii) and (i)

Answer 1

The correct option is A (i)

The refractive index of a prism is more for shorter wavelengths (violet) than for longer wavelengths (red).

Therefore, a colour with a shorter wavelength (violet) deviates more than that with a longer wavelength (red).
