Embibe Experts Solutions for Chapter: Dual Nature of Radiation and Matter, Exercise 1: Exercise

Identify the process in which an electron escapes from the metal surface.

Thermionic emission is the liberation of _____ from an electrode by virtue of its temperature.

Ultraviolet light falls on metal surface then electrons are emitted named as

Potential difference applied to an X -ray tube is $5\mathrm{kV}$ and the current through it is $3.2 \mathrm{mA}$. The number of electrons striking the target per second is Take $e=1.6\times {10}^{-19}\mathrm{C}$

In a photoelectric effect experiment, the slope of the graph between the stopping potential and the incident frequency will be of the order of

The photoelectric emission could be explained by the$—$

In an experiment on the photoelectric effect, the following graphs were obtained between the photoelectric current (I) and the anode potential (V). Name the characteristic of the incident radiation that was kept constant in this experiment.

The maximum kinetic energy of electrons emitted in the photoelectric effect is linearly dependent on the _______________ of the incident radiation.
