Define anti-aliasing
What do you understand by the term anti-aliasing? Describe briefly?
Expert
Anti-aliasing is a technique for enhancing the realism of an image by eliminating the jagged edges from it. Such jagged edges or jaggies appear as a computer monitor has square pixels, and such square pixels are inadequate for exhibiting lines or curves which are not parallel to the pixels and other reason is low sampling rate of the image information, which in turn leads to such jaggies.
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.

Young's experiment: double-slit experiment (T. Young; 1801): A well-known experiment that exhibits the wave nature of light (and certainly of other particles). The light is passed from a small source into an opaque screen with the two thin slits. The
Planck radiation law: The law which explained blackbody radiation better than its precursor, therefore resolving the ultraviolet catastrophe. This is based on the supposition that electromagnetic radiation is quantized. Q : Define Planck constant Planck constant Planck constant: h: The basic constant equivalent to the ratio of the energy of a quantum of energy to its frequency. This is the quantum of action. This has the value 6.626 196 x 10-34 J s.
