Question

White light can be separated into its components because

• A. Each ray of color is deviated by the prism by a different amount.
• B. Each ray of color is deviated by the prism by the same amount.
• C. Few rays of color are deviated by the prism by the same amount and others by a different amount.
• D. None of these

Answer 1

The correct option is A Each ray of color is deviated by the prism by a different amount.

Since each component of white light has a different wavelength, the refractive index of prism material will be different for components. Therefore, the angle of refraction for different components will be different. This will cause the splitting of components.

Hence-(A)
