Waves+n+EM+Spectrum

back (Remember to do the questions and summary) 1. Wave = a disturbance that transfers energy from place to place 2. Energy = the ability to do work 3. Medium = the material through which a wave travels 4. Crest = high point of a wave 5. Trough = low point of the way 6. Amplitude = the maximum distance the particles of the medium carrying the way move away from their resting positions. ( How far a wave goes above or below the medium's resting position.) 7. Wavelength = the distance between two corresponding parts of a wave 8. Frequency = # of complete ways to pass a given point in a certain amount of time. 9. Hertz = unit of frequency equaling the number of waves in a second 10. Electromagnetic Spectrum = the complete range of electromagnetic waves placed in order of increasing frequency 11. Visible light = electromagnetic waves that you can see Know this: Red/yellow/orange/green/blue/indigo/violet
