Question

Which of the following surfaces is correctly matched to the type of reflection taking place from it?

• A. Desert sand - Regular reflection
• B. Polished table top - Diffused reflection
• C. Glass window pane - Regular reflection
• D. Disturbed water surface- Regular reflection

Answer 1

The correct option is C Glass window pane - Regular reflection

When all the parallel rays reflected from a rough or irregular surface are not parallel, the reflection is known as diffused or irregular reflection. Desert sand, disturbed water surface and rough road are some examples where diffused reflection takes place. On the other hand, reflection from a smooth surface like a mirror, glass or polished surface is called regular reflection. The incident parallel rays remain parallel even after reflection.
