It is a type of vacuum tube which displays images when the electron beam through electron guns are strikes on the phosphorescent surface. Physical optics deals primarily with the nature and properties of light itself. A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. Geometrical optics has to do with the principles that govern the image Thermistors are divided based on their conduction model. Thermionic emission is the liberation of electrons from an electrode by virtue of its temperature (releasing of energy supplied by heat).This occurs because the thermal energy given to the charge carrier overcomes the work function of the material. .
