Simple definition of the Barkhausen Effect.
Brief description of Stokes' law and edge effects.
Details of how large planets have been detected around three other solar type stars. Understanding Doppler wobble aided by an exercise.
This applet shows interference effects with waves.
Different parts of the electromagnetic spectrum have very different effects on different things.
Vary the velocity and notice the wavelength shift ahead of and behind the source. A shock wave, i.e., sonic boom, can be seen to form if the speed of the source is comparable to the phase velocity.
Doppler studies of this blue supergiant in Cygnus indicate a period of 5.6 days in orbit around an unseen companion. The mass of the companion is calculated to be 8-10 solar masses, much too large to ...
A brief explanation how scientists find exoplanets from the radial method, to measuring Doppler shifts to measure drops in the intensity of light from stars.
A simple experiment to demonstrate the effects of pressure and how gases work.
Space weather effects on technology such as GPS, power systems, submarines, satellites, planes and more.
