Question

Which of these indicates the splitting of different colours of light in a prism?

• A. Reflection of light
• B. Dispersion of light
• C. Diffraction of light
• D. Refraction of light

Hint:

Dispersion occurs when light passes through a medium like a prism, causing different wavelengths to spread out and form a spectrum, as seen with a rainbow.

Answer 1

The Correct Option is B

The splitting of light into different colours (or wavelengths) when it passes through a prism is known as dispersion. This occurs because different wavelengths of light bend by different amounts when they pass through the prism, creating a spectrum of colours. Thus, the correct answer is \( \boxed{\text{Dispersion of light}} \).
