Refraction is when light bends as it passes from one material to another, like from air into water or glass. This bending happens because light travels at different speeds in different materials. The amount of bending depends on the angle at which the light hits the surface and the properties of the two materials. Refraction is why objects underwater look distorted or broken when you see them from above!
Match each term with its definition:
| Term | Definition |
|---|---|
| 1. Refraction | A. The line perpendicular to the surface where light enters. |
| 2. Angle of Incidence | B. The bending of light as it passes from one substance to another. |
| 3. Angle of Refraction | C. The angle between the refracted ray and the normal. |
| 4. Normal | D. The material light passes through. |
| 5. Medium | E. The angle between the incident ray and the normal. |

Complete the sentences using the words: bending, slower, refraction, angle, speed.
(Answers: 1-refraction, 2-speed, 3-bending, 4-slower, 5-angle)
Explain how refraction makes a straw in a glass of water look bent or broken. Use the words 'light', 'bending', and 'water' in your explanation.
(Answer: When light travels from the water to our eyes, it undergoes bending due to refraction. The bending of light as it exits the water causes the straw to appear bent or broken at the point where it enters the water.)
