MJHS7 Waves and Ener
MJHS7 Waves and Energy Vocabulary
| Question | Answer |
|---|---|
| Distance between two identical parts of a wave (crest to crest or trough to trough) | wavelength |
| A regular repeating pattern of motion in which energy is transferred; caused by a disturbance that creates a vibration | wave |
| Number of waves that pass a point in one second; measured in Hertz (Hz) | frequency |
| Wave consisting of compressions and rarefactions such as sound | longitudinal wave |
| Waves produced by an earthquake | seismic waves |
| When atoms are smashed together or broken apart | nuclear reactions |
| A large water (ocean) wave caused by an earthquake | tsunami |
| Wave consisting of crests and troughs such as light | transverse wave |
| Transverse waves that transfer electric and magnetic energy; do not require a medium; same speed but different wavelengths and frequencies | electromagnetic waves |
| The ability to do work | energy |
| Lognitudinal wave that needs a medium to travel through; slower than light; faster in solids; faster in higher temperatures | sound wave |
| A repeated back-and-forth or up-and-down motion caused by a disturbance | vibration |
| Maximum distance a medium moves away from its rest position; measurement of the energy in a wave | amplitude |
| Waves produced by nuclear reactions on the sun such as radio waves, visible light, and x-rays | sun's radiation |
| Type of electromagnetic wave visible to the human eye; faster than sound | light energy |
