Assertion :Statement I: Though the light of a single frequency (monochromatic light) is incident metal, the energies omitted photoelectrons are different. Reason: Statement Il: The energy of electrons just after they absorb photons incident on the metal surface may be lost a collision with other atoms in the metal before the electron is ejected out of the metal.
The energy of electrons just after they absorb photons incident on the metal surface may be lost in a collision with other atoms in the metal before the electron is ejected out of the metal which results in the ejected photoelectrons with different energies despite monochromatic incident radiation.
Hence Reason is the correct explanation of Assertion.
de Broglie wavelength associated with a gas molecule varies as, λ∝1/√T.
