Which of the following is NOT an example of refraction in physics? A coin at the bottom of a water cup A pencil inside a water cup. Rainbows Shining a flashlight down a hallway. A straw in a water cup
Understand the Problem
The question asks which of the following options is not an example of refraction. Refraction is the bending of light (it also happens with sound, and water waves) as it passes from one medium to another.
Answer
Shining a flashlight down a hallway.
Shining a flashlight down a hallway is not an example of refraction. Refraction is the bending of light as it passes from one medium to another. Shining a flashlight down a hallway involves the propagation of light in a single medium (air) without a change in direction due to a change in medium.
Answer for screen readers
Shining a flashlight down a hallway is not an example of refraction. Refraction is the bending of light as it passes from one medium to another. Shining a flashlight down a hallway involves the propagation of light in a single medium (air) without a change in direction due to a change in medium.
More Information
Refraction is responsible for many optical illusions, such as the apparent bending of a straw in a glass of water.
Tips
Remember that refraction involves light changing direction as it moves from one substance (like air) to another (like water or glass).
