This equation, Bragg's law, describes the condition on θ for constructive interference. [12] A map of the intensities of the scattered waves as a function of their angle is called a diffraction pattern. Strong intensities known as Bragg peaks are obtained in the diffraction pattern when the scattering angles satisfy Bragg condition.
Radar angels are an effect seen on radar displays when there is a periodic structure in the view of the radar that is roughly the same length as the signal's wavelength.The angel appears to be a physically huge object on the display, often miles across, that can obscure real targets.
The principle of operation behind RASS is as follows: Bragg scattering occurs when acoustic energy (i.e., sound) is transmitted into the vertical beam of a radar such that the wavelength of the acoustic signal matches the half-wavelength of the radar. As the frequency of the acoustic signal is varied, strongly enhanced scattering of the radar ...
A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence the name). [ 1 ]
After Dark is a series of computer screensaver software introduced by Berkeley Systems in 1989 for the Apple Macintosh, and in 1991 for Microsoft Windows. [3] [4]Following the original, additional editions included More After Dark, Before Dark, and editions themed around licensed properties such as Star Trek, The Simpsons, Looney Tunes, Marvel, and Disney characters.
2. Click the Desktop & Screen Saver icon. 3. Next to Start screen saver, click and drag the slider back and forth from the minimum amount of time to the maximum amount of time several times. This will activate the client and enable the user to complete the setup.
Scattering also includes the interaction of billiard balls on a table, the Rutherford scattering (or angle change) of alpha particles by gold nuclei, the Bragg scattering (or diffraction) of electrons and X-rays by a cluster of atoms, and the inelastic scattering of a fission fragment as it traverses a thin foil.
