Correct answer and explanation

Correct answer: Refraction

Explanation: āœ… Correct Answer: B) Refraction šŸ“š Explanation: Refraction occurs because light changes its speed when it enters a medium with a different optical density. This causes the light path to bend, which is why a pencil half-submerged in water appears broken or bent at the surface. Lenses in cameras, microscopes, and human eyes all rely on refraction to focus light and form images.
