| Question | Answer |
| What is a wave? | A wave is a traveling disturbance of coordinated vibrations that transmit energy with no movement of matter. |
| What are Mechanical waves? | Mechanical waves are waves that require a material through which to travel. |
| What are Electromagnetic waves? | Electromagnetic waves propagate along electric and magnetic field lines and to not need a material through which to travel. |
| What does periodic motion mean? | It will repeat itself. |
| What is a continuous wave? | Continuous waves are caused by a repetitive disturbance. |
| What is a pulse? | A single "bump" of a wave |
| What is the amplitude of a wave? | The maximum displacement from the equilibrium. |
| What is the crest? | The crest is the highest point of the wave. |
| What is the trough? | The trough is the lowest point of the wave. |
| What is that wavelength? | The wavelength is the distance between two repetitive points on the wave. |
| What is frequency? | The number of waves that pass a point in space in one second. |
| What is the equation for frequency? | f= 1/t |
| What is a transverse wave? | A transverse wave is a type of mechanical wave. It occurs when the motion of the particles of the medium move perpendicular to the motion of the wave. |
| What is a longitudinal wave? | A longitudinal wave is when the particles of the medium move parallel to the motion of the wave. |
| What is the electromagnetic spectrum? | The range of electromagnetic radiation. |
| Where do light rays combine? | In the additive color wheel. |
| Where do paints combine? | In the subtractive color wheel. |
| What is reflection? | When light bounces off of the boundary of a new material. |
| What is specular reflection? | When light bounces off of a smooth surface. |
| What is diffuse reflection? | When light bounces off of a rough or textured surface. |
| What is the focal point? | The focal point is the point where incoming parallel light rays converge or the point from which they diverge. |
| What is the focal length? | The distance from the mirror to the focal point. |
| What is refraction? | When light is transmitted into a new material. |
