Integer (computer science) In computer science, an integer is a datum of integral data type, a data type that represents some finite subset of the mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits (bits).
critical angle. Definition: The angle or greater, measured at the interface between a denser medium and a less dense in the same plane as the incident light, at which total internal reflection takes place - i.e. light is reflected back into the medium.
Definition. No. If there is no change in speed there is no refraction. If there is no refraction, there is no dispersion of light and hence, no rainbow! Term. The minimum angle of incidence for which a light ray is totally reflected within a medium is called the ______________ _______________. Definition. critical angle. Term. The 100% reflection (with no transmission) of light that strikes the boundary between two media at an angle greater than the critical angle is called _______ ________ ________.
