In velocity modulation, three cases are taken. Firstly, there is no applied voltage and as such electrons passing through the gap A are unaffected and will reach the collector with the same constant velocities.... read more

Klystron is the simplest vacuum tube that can be used for amplification or generation of microwave signal. The operation of klystron depends upon velocity modulation which leads to density modulation..... read more

Visible and U.V. spectroscopy have a number of applications. Some of them are- 1. Assignment of structure of compounds: If two compounds show same absorption spectra means they should same structure. If structure of one of them is known, other’s can be determined which can be illustrated by the following example.... read more

Einstein or photochemical equivalence law is applicable only to the primary photochemical process or in other words as a result of primary absorption of one quantum, only one molecule undergoes dissociation and the products enter no further reaction... Read more
