Explanation Given: The bond energy of the electron in ground state is B E = − E 0 . The kinetic energy of the ejected electron is K E = 2 E 0 . Formula used: The conservation of energy of electron is given by E = K E − B E The energy of the photon is given by E = h c λ Calculation: The conservation of energy of electron is calculated as follows: E = K E − B E = 2 E 0 − ( x

Particle Theory of Light

The particle theory of light was the proposal made by Newton in 1704 in his treatise Opticks. This is the most basic light theory, in which light is thought to be made up of microscopic particles known as "corpuscles" and that's why this particle theory …

Stopping Potential

In an experiment conducted by Heinrich Hertz, an apparatus was made where the incident light was made to fall on the metallic plate, it was discovered that metals emit electrons. The surface electrons are bound to metals with a minimum amount of energy a…

Quantization of Charges

An electron is a negatively charged subatomic particle either attached to an an atom or sticks to the nucleus of the atom. Electrons exert the negative charge that tries to balance the positive charge of the nucleus.
