The RF propagation software provides efficient and accurate predictions of EM propagation and communication channel characteristics in complex urban, indoor, rural and mixed. waves are meeting at some point p at the same time the only difference occurs in their phases. Use an on-line simulation from the University of Colorado PhET group to explore the behavior of waves on a string. If high amplitudes overlap, the amplitude of the total wave is the sum of them, and the same happens with low amplitudes, resulting in the light bands. Because the disturbances add, the pure constructive interference of two waves with the same amplitude produces a wave that has twice the amplitude of the two individual waves, but has the same wavelength. Thomas Young observed interference of light and measured the wavelength of light in this classic experiment performed around 1801. Schakowsky, Mr. Snowflakes simulations.
