Learning Objectives. Explain how energy travels with a pulse or wave. Describe, using a mathematical expression, how the energy in a wave depends on the amplitude of the wave. All waves carry energy, and sometimes this can be directly observed.
In addition to this tutorial, we also provide revision notes, a video tutorial, revision questions on this page (which allow you to check your understanding of the topic) and calculators which provide full, step by step calculations for each of the formula in the Energy and Power of Waves tutorials.
Learning Objectives. By the end of this section, you will be able to: Explain how energy travels with a pulse or wave. Describe, using a mathematical expression, how the energy in a wave depends on the amplitude of the wave. All waves carry energy, and sometimes this can be directly observed.
16.4 Energy and Power of a Wave. Consider a string with under tension with a constant linear mass density. A sinusoidal wave with an angular frequency and amplitude produced by some external driving force. If the frequency of the driving force is decreased to half of the original frequency, how is the time-averaged power of the wave affected?
