Debroglie Wavelength #!#Force due to Photons#!#IIT Advanced PYQs

Debroglie wavelength of a particle at rest position is

When wavelength of incident photon is decreased then

Debroglie wavelength of uncharged particles depends on

Debroglie wavelength of a moving gas molecule is

Debroglie wavelength of proton accelerated by an electric field at a potential difference v is

The debroglie wavelength of an electron is lambda and has energy E. If the debroglie wavelength is reduced by 25% then how much extra kinetic energy will the electron have now?

If debroglie wavelength is same for an electron and proton, then which of the following relation is correct

When photons of energy 4.25eV strike the surface of a metal A, the ejected photoelectrons have maximum kinetic energy, T_A (expressed in eV) and deBroglie wavelength lambda_A . The maximum kinetic energy of photoelectrons liberated from another metal B by photons of energy 4.20V is T_B = T_A -1.50eV . If the deBroglie wavelength of those photoelectrons is lambda_B = 2lambda_A then
