Electrons Crossword Puzzle

QUESTIONS LIST: conductivity : the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field which causes the flow of current, insulator : a substance or device which does not readily conduct electricity, electron : a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids, optics : the scientific study of sight and the behaviour of light, or the properties of transmission and deflection of other forms of reflections, scattering : the process in which electromagnetic radiation or particles are deflected or diffused, reflection : when a ray of light approaches a smooth polished surface and the light ray bounces back, wavelength : the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave, interference : what happens when two or more waves meet each other. depending on the overlapping waves’ alignment of peaks and troughs, they might add up, or they can partially or entirely cancel each other, charge : property of matter that causes it to experience a force in an electromagnetic field, spectrum : a continuum of color formed when a beam of white light is dispersed by passage through a prism so that its component wavelengths are arranged in order, semiconductor : materials which have a conductivity between conductors and insulators, doping : add an impurity to a semiconductor to produce a desired electrical characteristic.
