1. Mr. P, Physical Science

2. (said “lambda”) Symbol meaning “wavelength”

3. TT Symbol meaning “change in temperature”

4. Amplitude Distance from rest to crest in a transverse wave

5. Calorimetry The study of heat energy

6. Compression Part of a longitudinal wave where the medium is most “crunched” together and the energy is highest

7. CpCp Symbol meaning “specific heat capacity”

8. Crest The highest position of a transverse wave

9. Endothermic Describes a situation where heat is absorbed (it will feel cold)

10. Exothermic Describes a situation where heat is released (it will feel hot)

11. Frequency The number of waves that occur in a certain amount of time (usually per second)

12. Longitudinal Wave A 1-dimensional wave; the particles of the medium move parallel to the direction that energy is traveling

13. Medium The empty space or substance that a wave travels through

14. Q Symbol meaning “amount of heat”

15. Rarefaction Part of a longitudinal wave where the medium is least “crunched” together and the energy is lowest

16. Specific Heat Capacity The amount of heat (in Joules) needed to raise 1 g of a substance 1 °C

17. System Parts working together using energy; can be “closed” or “open”

18. Transverse Wave A 2-dimensional wave; the particles of the medium move perpendicular to the direction that energy is traveling

19. Trough The lowest position of a transverse wave

20. Wave These are evidence that energy is traveling from place to place

21. Wavelength Distance from compression to compression in a longitudinal wave, or crest to crest in a transverse wave
