Waves and Energy
Waves carry energy. The amount of energy they carry is related to their
frequency and their amplitude. The higher the frequency, the more energy, and
the higher the amplitude, the more energy.
WAVES: A wave is a propagating dynamic disturbance of one or more quantities.
Waves can be periodic, in which case those quantities oscillate repeatedly
about an equilibrium value at some frequency.
