When white light hits the prism, different colors turn from different angles. Which of these seven colours deviates the least and most respectively?

The correct answer is Red color and purple color

Key Points

• When white light hits a prism, the light is dispersed into its constituent colors, each bending at a different angle due to their varying wavelengths.
• The deviation depends on the wavelength of the color: shorter wavelengths (violet) deviate more, and longer wavelengths (red) deviate less.
• Least deviation: Red color
• Most deviation: Violet color (often referred to as purple)
• Therefore, the correct option is: Red color and purple color
