Reflection and Refraction
| Question | Answer |
|---|---|
| What way to convex mirrors curve? | outward |
| What is a likeness or a reproduction of an object? | an image |
| What happens when sound energy is not reflected? | It is absorbed or transmitted |
| What is the bending of a wave as it crosses the boundary between two media and an angle? | refraction |
| What happens when you shine a beam of light on a mirror? | It does not travel through it, it is returned back through the air |

| What is an angle between an incident ray and the normal to a surface? | angle of incidence |
| What is the angle between a reflected ray and to normal to a surface? | Angle of reflection |
| What is the reflections of waves in many directions from a rough surface | diffuse reflection |
| What is a persistence of a sound as in an echo due to multiple reflections? | reverberations |
| What image can be seen only at certain angles because it is reflected in an orderly pattern? | a smooth mirror |
