Veritasium – Why Gravity is NOT a Force

Posted on October 16, 2020 by VCE Physics

The General Theory of Relativity tells us gravity is not a force, gravitational fields don’t exist. Objects tend to move on straight paths through curved spacetime.

oPhysics: Double Slit Interference

Posted on October 8, 2020 by VCE Physics

This is a simulation of diffraction of light by a double slit. Use the sliders to adjust the distance between the slits and the wavelength of the light. Use the checkboxes to show or hide the wavefronts, maxima, and vertical scale. Use the Show Interference Pattern button to create the interference pattern that would be seen on the screen. Note that the distances in the simulation are all very small, so that you can see the wavelength separations. The y distances shown in the scale and the distance from the slits to the screen (L) are proportional, so they can just be thought of as meters or any other convenient unit.

Interference Demo: Speakers

Posted on August 11, 2020 by VCE Physics

This is a demonstration of the interference pattern created by two speakers playing the same 2000 Hz tone. It is carried out by moving a microphone through the sound field and noting that the sound is louder in some spots (those with constructive interference) than others.

This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.
