This bends white light and separates it into different colors of light.

• A. Lens
• B. Prism
• C. Mirror
• D. Filter

Answer: (B)

Light can bend when it enters a material, and different colors bend by different amounts. A prism uses this idea to spread white light into a spectrum because each color slows and bends by a slightly different amount as it passes through the glass. Red light bends the least and violet the most, so the colors fan out into a rainbow. Other options don’t create that rainbow effect. A lens changes the direction of light to focus it but doesn’t separate white light into its colors. A mirror simply reflects light. A filter changes which colors pass through but doesn’t split a beam into separate colors.
