planning and carrying out your own experiments on a variety of topics in the lab manual, you will hopefully learn biology by satisfying your own curiosity. In this AP lab manual, the inquiry-based structure includes the following components:
The objective of the experiment is to understand the physical phenomena of wave energy, the methods for converting the energy of the wave to useful energy forms, and gain the understanding of simple engineering calculations regarding wave energy.
waves carry the destructive forces of earthquakes. In this lab you will have the opportunity to explore various wave phenomena to help you organize your experiences with mechanical waves. We will build on our experiences from the last laboratory by using springs as the medium for our waves.
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.
Energy in Wave Motion. 1 dimensional: wave on a string. y F = − ) t , x ( F ∂ y ( x , t ) ∂ x. For any wave on a string, instantaneous rate of energy transfer. F =− ) t y y , x ( v ) t , x ( F ) t , x ( P = ∂ y ( x , t ) ∂ y ( x , t ) ∂ x ∂ t. Energy Transferred by Sinusoidal Wave. For a sinusoidal wave. ( x , t ) = A cos( kx − ωt ) t , x )
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.
A wave is a traveling form of energy that carries oscillations from one place in space to another. Sound and light are waves and share characteristics of frequency and wavelength with familiar water waves.
