LOTS 5: Waves and Calorimetry
Mr. P, Physical Science
(said “lambda”)Symbol meaning “wavelength”
TSymbol meaning “change in temperature”
AmplitudeDistance from rest to crest in a transverse
wave
CalorimetryThe study of heat energy
CompressionPart of a longitudinal wave where the medium
is most “crunched” together and the energy is highest
CpSymbol meaning “specific heat capacity”
CrestThe highest position of a transverse wave
EndothermicDescribes a situation where heat is absorbed
(it will feel cold)
ExothermicDescribes a situation where heat is released
(it will feel hot)
FrequencyThe number of waves that occur in a certain
amount of time (usually per second)
Longitudinal WaveA 1-dimensional wave; the particles of the
medium move parallel to the direction that energy is traveling
MediumThe empty space or substance that a wave
travels through
QSymbol meaning “amount of heat”
RarefactionPart of a longitudinal wave where the
medium is least “crunched” together and the energy is lowest
Specific Heat CapacityThe amount of heat (in Joules) needed to
raise 1 g of a substance 1 °C
SystemParts working together using energy; can be
“closed” or “open”
Transverse WaveA 2-dimensional wave; the particles of the
medium move perpendicular to the direction that energy is traveling
TroughThe lowest position of a transverse wave
WaveThese are evidence that energy is traveling
from place to place
WavelengthDistance from compression to compression in
a longitudinal wave, or crest to crest in a transverse wave
