LIGHT WAVES That part of the electromagnetic spectrum that contains visible light. The colors, from longest wave length to shortest, are red, orange, yellow, green, blue, indigo, and violet (ROY G. BIV). Related term: visible light ...
When ultraviolet light waves (UV) strike CFC* (CFCl3) molecules in the upper atmosphere, a carbon-chlorine bond breaks, producing a chlorine (Cl) atom.
DIFFRACTION The result of light waves interfering with other after passing through a narrow aperture, causing them to bend or spread. DIRECTIONAL SHEAR The shear created by a rapid change in wind direction with height.
Optical effects resulting from diffraction are produced through the interference of light waves. To visualize this, imagine light waves as water waves.
The longer wavelengths, like red, continue more or less unimpeded to the surface (4). The blue light waves are scattered all over the sky up and down in all directions.
Doppler Effect (aka Doppler Shift) The apparent change in frequency of sound or light waves, varying with the relative velocity of the source and the observer. If the source and observer draw closer together, the frequency is increased.
