Black uniformity refers to a TVâs ability to display solid black all across its screen. Perfect black uniformity would mean shadows, night skies, and other black objects would look equally dark at any given point on the screen, and that the TVâs lighting is perfectly diffused across the screen.
The Doppler Effect for light is the change in the observed frequency or wavelength/color compared with that emitted from a moving source. Note: Typically, the observed frequency is measured in the Doppler Effect. However in same cases, the change in wavelength is measured.The source of light or electromagnetic radiation must travel at a high speed for the Doppler effect to cause an observable shift in the frequency and wavelength.Since the speed of light is much greater than the speed of the source, an approximate equation can be used to determine the shift of the radiation.The shift in wavelength is used in astronomy to tell when a distant galaxy or star is moving toward the Earth (blue-shift) or away (red-shift).ince the speed of light is much greater than the speed of the source, an approximate equation can be used to determine the shift of the radiation.
