When white light is dispersed into its seven-colour components by a prism, which color of light bends the least?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Red
When white light passes through a prism, different colours bend by different amounts due to dispersion.
Red light has the longest wavelength and hence the lowest refractive index, so it bends the least.
Violet light bends the most.
