Java applet showing constructive and destructive interference between two longitudinal waves, the wavelength and amplitude of each of which can be altered by the user.
The site is an interactive page to study the photoelectric effect on different materials (sodium, cesium and silver) by changing the wavelength and the intensity of the light.
A Java applet of a wave where you can adjust its wavelength, frequency, and amplitude by clicking on the drop down list in the upper left corner, and then selecting one of the choices which appear.
Detailed description of Bremsstrahlung, includes a graph illustrating intensity/wavelength relationship. Part of a larger site which includes many definitions and links.
Historical background and online tutorials on diffraction in which you can vary wavelength and aperture width, and see the results as wave fronts, and as an intensity graph. Explanations include the ...
An explanation of Doppler shift, which occurs when the light emitted by a moving star for example changes wavelength (known as redshift or blueshift).
The region just below the visible in wavelength is called the near ultraviolet. It is absorbed very strongly by most solid substances, and even absorbed appreciably by air.
Describes Wien's Displacement Law and the relationship between wavelength and temperature for black body radiation.
Animated diagrams of two superposing transverse waves and their resultant. Wavelength, phase and amplitude are adjustable. Uses the word "interference" instead of "superposition".
This java applet let you play with two point sources and watch the effect of interference. Wavelength can be changed and path length is shown.
