Title: Reflection and Transmission of Waves
Category: Reflection and Transmission of Mechanical Waves
Summary: This learning object discusses the concepts behind the reflection and transmission of waves, and includes a brief explanation of ultrasound imaging. The aim of this LO is to provide insight not only into when a wave is inverted upon reflection, but why a wave is or is not inverted upon reflection.
At 2:40 in the video, I said that the amplitudes of transmitted and reflected waves add up to equal the amplitude of the incident wave. I meant that the energies of transmitted and reflected waves add up to equal the energy of the incident wave. It is energy that is conserved, not amplitude.
