| carries energy without carrying matter | wave |
| wave requires matter to carry energy | mechanical wave |
| sound is an example of this | mechanical wave |
| requies no matter to carry energy | electromagnetic wave |
| light is an example of this wave | electromagnetic wave |
| vibrates perpendicular to direction its moving | transverse wave |
| electromagnetic wave is an example of this | transverse wave |
| vibrates same direction its moving | compressional wave |
| sound is an example of this wave | compressional wave |
| produced by vibrations of vocal chords | talk or sing |
| 1/2 distance between crest and trough | amplitude |
| measure of energy a wave carries | amplitude |
| crest to crest or trough to trough | wavelength |
 | wavelength |
 | electromagnetic spectrum |
| ROYGBIV | visible light |
| radio waves, mocrowaves, x-rays, gamma rays | electromagnetic spectrum |
| wavelength and frequency | inversely proportional |
| longer wavelength/lower frequency wave | red light |
| high frequency/shorter length wave | violet light |
| number of waves pass a given point in 1 sec | frequency |
| 340 m/s in air | sound waves |
| 300,000,000 m/s in air | light waves |
 | equation for speed of light |
| bouncing of waves | reflection |
 | reflection |
| bending of waves from 1 medium to another | refraction |
 | refraction |
 | normal/wave slowing |
| bending of waves around a barrier | diffraction |
 | diffraction |
| sound more than light | better diffraction |
