Explanation Write the equation for the maximum kinetic energy of the photoelectrons K = 1 2 m v max 2 Here, K is the maximum kinetic energy of the photoelectrons, m is the mass of electron and v max is the maximum speed of the photoelectrons Rewrite the above equation for v max . v max = 2 K m (I) The maximum kinetic energy of the photoelectrons is the energy of the photon absorbed minus the work function of the metal. K = h f − ϕ (II) Here, h is the Planck’s constant, f is the frequency of the photon and ϕ is the work function of the metal Write the equation for the frequency of the photon. f = c λ Here, c is the speed of light in vacuum and λ is the wavelength of the photon Put the above equation in equation (II). K = h c λ − ϕ (III) Conclusion: Given that the wavelength of the light is 235 nm . The value of h is 4.136 × 10 − 15 eV ⋅ s , the value of c is 3.0 × 10 8 m/s , the mass of electron is 9.11 × 10 − 31 kg and the work function of nickel is 5.1 eV . Substitute 4.136 × 10 − 15 eV ⋅ s for h , 3.0 × 10 8 m/s for c , 235 nm for λ and 5.1 eV for ϕ in equation (III) to find K . K = ( 4.136 × 10 − 15 eV ⋅ s ) ( 3

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.
