| Question | Answer |
|---|---|
| When waves strike the surface of a transparent medium, like water at an angle the direction changes. | This is refraction. |
| When light shines perpendicularly on the surface of still water how much of its energy is reflecteed? | 2% is reflecteds and the rest is transmitted. |
| When light strikes glass perpendicularly how much of its energy is reflected? | 4% is reflected and the rest is transmitted |
| What does the Law of Reflection state? | It says that the angle of incience and the afngle of reflection are equal to each other. |
| What is a light wave that strikes a boundary called? | It is called and incident wave. |
| How is incident wave's path drawn? | The path is drawn as a staight line arrow. |
| What is the straight line with an arrow called? | It is called an incident ray. |
| What is a light wave that bounces off a boundary called? | It is called a reflected wave. |
| How is the reflected wave drawn? | It is drwan as a reflected ray. |
| A line drawn perpendicular to the point where the incident ray strikes the barrier is called the what? | It is called the normal. |
| How is the normal drawn? | It is dran as a dashed line. |
| Will the angle of incidence always equal the angle of reflection? | Yes, it will. |
| Where does a virtual image appear? | It appears to be in a location where ligt does not really reach. |
| What kind of images does a plane mirrow show? | It only show virtual images. |
| What kind of mirror curves outward? | A convex mirror. |
| What kind of mirror curves inward? | A concave mirror. |
| Are virtual images usually upright or inverted? | Virtual images are usually upright. |
| Are real images usually inverted? | Yes, they are. |
| What is diffused reflection? | It is the reflection of light from a rough surface. |
