| A | B |
|---|
| Wavelength | Distance from crest to crest |
| Gamma | Shortest EM wavelength |
| Radio | Longest EM wavelength |
| UV | Radiation that causes sunburn |
| Frequency | As wavelength increases this decreases |
| Sun | A natural source of EM energy |
| Visible light | Type of EM energy that can be seen |
| Red | Visible light with longest wavelength |
| Violet | Visible light with shortest wavelength |
| ROYGBIV | Sequence of visible light spectrum |
| Indigo | What the I stands for in ROYGBIV |
| Prism | Instrument to break white light into colors |
| Spectrum | The total array of electromagnetic energy types is the EM -?- |
| Sound | Has waves but is not part of electromagnetic radiation |
| Refraction | The bending of EM radiation as it travels from one medium to another |
| Reflection | According to the law of reflection, the angle of incidence always equals the angle of -?- |
| Amplitude | As wave height increases, this increases |
| White | If all the colors of visible light are combined, this color is produced |
| Microwave | EM wavelength used to cook food and for cell phone transmission |
| Second | Frequency is measured in cycles per -?- to pass a point |
| Black | Color that absorbs the most visible light |
| Heat | Infrared radiation is associated with the production of |
| Speed | The -?- of light decreases as it moves from space into water |
| Hertz | Unit in which frequency is measured |
| Space | As EM radiation passes through this, it travels at the speed of light |
| X Rays | Form of energy between gamma rays and UV rays on the EM spectrum |
| Reflected | The color of an object comes from the visible light that is |
| Black | When all visible light is absorbed, a material's color appears to be |
| Transparent | When all light passes through an object it is said to be |
| White | This color object reflects almost all visible light colors |
| Absorbed | Light that does not pass through an object and is not reflected is |
| Refraction | As light waves pass from air into water, they bend, which is called |
| Decreases | The speed of EM waves does this as they move from the vacuum of space into a medium |
| Red | John shines a white light through red glass, what color of light will pass out the other side? |
| Shortest wavelength | When sunlight passes through the atmosphere, which wavelength scatters the most? |
