The Doppler effect
Brilliant animations: an excellent site bringing the maths alive. All D Russell's work is rated most highly by teacher panels.
Detect The Jupiter Like Planet Around Three Stars
Details of how large planets have been detected around three other solar type stars. Understanding Doppler wobble aided by an exercise.
Doppler Physlet
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.
Cygnus X-1
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 ...
Biography of Johannes Stark
Johannes Stark (1874 - 1957) received the Nobel Prize for Physics in 1919 for his discovery of the Doppler effect in canal rays and of the splitting of spectral lines in electric fields.
Moving Point source: Doppler effect and shock wave
An animation to illustrate the propagation of sound waves from a moving source. You can modify the wave speed, the source speed and wavelength.
How radar works
What radar is and how it works, including doppler radar and how to hide from military radar.
