WebApr 5, 2024 · An emission spectrum is the range or array of wavelengths (spectra) obtained when the light emitted by a substance is passed through a prism and examined directly with a spectroscope. Now let's define the line emission spectrum: a spectroscope splits the emitted light into different wavelengths and gives a discontinuous spectrum in … WebJan 26, 2024 · Extrinsic Semiconductor: Definition, Properties & Types. Extrinsic Semiconductor: Semiconductors belong to a class of crystalline solids that are intermediate in electrical conductivity between a conductor and an insulator. Semiconductors have a small energy gap between the valence band and the conduction band. WebThe valence electrons should have the same energy as the energy gap to move from the valence to the conduction band. There are three major classifications in the energy bands which are – Valence band, Conduction band, Forbidden energy band. Conductors, Insulators and Semiconductors are the three major types of energy bands. calwin benefits account
