• Waves can transmit (carry) energy as they travel

• The amount of energy a wave transmits depends on its:

  • Frequency

  • Amplitude

Energy and Waves

• As the frequency of wave increases, the energy it transmits also increases

• "As frequency goes up, so does energy"

Frequency and Energy

• Each wave carries a certain amount of energy

• If the frequency goes up, that means more waves hit an object every second

• That means more energy is transmitted

Frequency and Energy

• As the amplitude of wave increases, the energy it transmits also increases

• "As amplitude goes up, so does energy"

Amplitude and Energy

• As the amplitude of a wave increases, so does its size

• A larger wave can transmit more energy

• So, energy increases as amplitude increases
