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.
Balmer series (J. Balmer; 1885): An equation that explains the emission spectrum of hydrogen whenever an electron is jumping to the next orbital; four of the lines are in visible spectrum, and the remainder (residue) are in the ultraviolet.
Solar water heating: Solar water heaters are simple, reliable, famous and widespread. They are probably the Low Carbon technology closest to being commercially practised. The most efficient designs concentrate solar radiation onto a small diameter tub
