The silver surface naturally gives rise to "free" electrons that can vibrate, or oscillate when they interact with light, which compresses the light down to nanometer scale.
As space compresses, the light's wavelength compresses, making it bluer; as it rarifies, the wavelength stretches, making it redder.
In all of these and following 3D views the resistivity anomaly occurrence probability scale has been modified, by compressing the light-to-dark colour sequence entirely within the positive half-scale and leaving colourless the negative half-scale. Figure 10 3D views of the probability-based ERT representation in the A-zone (a), B-zone (b), and C-zone (c).
The wobbles stretch or compress the wavelength of light from the star as seen from the Earth, making it redder as it moves away and bluer as it comes closer.
Whatever you do, please wear sunglasses if you are looking at that tiny circle where the light is compressed, (the damage is permanent!).
The light waves are compressed (blueshifted) in the direction of motion, and stretched (redshifted) opposed to the direction of motion.
The gamma rays from this primary move with the speed of light and compress the "secondary," a combination of lithium-6 (which rapidly decomposes to tritium and helium) and deuterium.
If it is emitted in the direction that the dust particle is travelling, the light waves will be compressed to have a slightly shorter wavelength (this is known as the Doppler effect).
In the direction that you're moving — or, alternately, the direction the environment appears to be moving toward you — the light's wavelength appears compressed, or shorter and bluer.
