LOTS 5: Waves and Calorimetry Mr. P, Physical Science

 (said “lambda”) Symbol meaning “wavelength”

T • Symbol meaning “change in temperature”

Amplitude • Distance from rest to crest in a transverse wave

Calorimetry • The study of heat energy

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

Cp • Symbol meaning “specific heat capacity”

Crest • The highest position of a transverse wave

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

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

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

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

Medium • The empty space or substance that a wave travels through

Q • Symbol meaning “amount of heat”

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

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

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

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

Trough • The lowest position of a transverse wave

Wave • These are evidence that energy is traveling from place to place

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