Power Point covering 4-1 Waves
Defines waves, mechanical waves, medium, transverse waves, crest, trough, wavelength, amplitude, frequency, compressional wave, compression,rarefaction, electromagnetic waves. Explains how the energy of a wave is proportional to the square of the amplitude.
Ex. If the height of the wave is doubled, each wave will have four times the energy.
Explains the amount of energy transferred by waves in a given time is proportional to frequency.
If twice as many waves hit the shore each minute, then twice as much energy will be transferred to the shore.
Could be edited for younger or older learners.
