< < Lecture 25 Lecture 27 > > Resources Visualizing video at the speed of light – MIT researchers created a video where you can see photons traveling through a medium. Finding the speed of light with peeps – Use your favorite marshmallow candy and a microwave to calculate the Read more…
< < Lecture 20 Lecture 22 > > Resources Colors of noise – You may have heard of white noise; there are many different “colors” of noise pertaining to the frequencies of sound contained within the noise. This wikipedia page allows you to listen to the different types of noise. Read more…
< < Lecture 19 Lecture 21 > > Resources Resonance – This 30 minute long video from The Mechanical Universe series demonstrates the concept of resonance using the notable Tacoma Narrows Bridge disaster. (Note: there is some consensus by experts that resonance was not the cause of the Tacoma Narrows Read more…
< < Lecture 18 Lecture 20 > > Resources Acoustics and vibrations animations – Check out these animations of different types of waves (longitudinal, transverse, etc.). Circular harmonics – Animations of circular harmonics, which are the waves that are created on a circular membrane, such as a drumhead. PhET Wave Read more…
