Statement-1:In compton effect, the scattered photon has wavelength more than the incident photon. Statement-2:Energy and momentum are conserved during the scattering of a photon by an electron.

Statement-1 : In photoelectric effect, the number of photoelectrons emitted is always equal to number of photons incident. and Statement-2 : All the photons fallin on the surface will eject photoelctron, is not necessary.

Statement-1: The smaller the wavelength of a photon, the more energy it has. Statement-2: The smaller the wavelength of a photon, the more momentum it has.

Statement-1: If an electron has the same wavelength as a photon, they have the same energy. Statement-2: by debroglie hypothesis p=h/lambda for both the electron and the photon.

When a beam of monochromatic light is passed through benzene , the spectrum of scattered radiations contains lines whose wavelengths (and frequencies ) are longer or shorter than that of the incident light . This phenomenon is known as

Statement-1: Kinetic energy of photoelectrons increases with increases in the frequency of incident radiation Statement-2: The number of photoelectrons ejected increases with increases in intensity of incident radiation.

Statement-1 : Partially transwave waves are possible on a liquid surface Statement-2 : Surface tension provide some rigidity on a liquid surface

Given below are two statements : Statement-I : Two photons having equal linear momentum have equal wavelengths. Statement-II : If the wavelength of photon is decreased, then the momentum and energy of a photon will also decrease. In the light of the above statements, choose the correct answer from the options given below.

Statement - 1: When white light (which contains all wavelengths) is passed through atomic hydrogen gas then transmitted beam is not having some wavelengths whose photons energy is equal to difference of two energy levels.This is due to absorbtion of photon by atom.The resulting excited atom then re-radiate photons in random direction with only a few in the same direction as of original beam of white light. Statement - 2: Momentum remains conserved during absorption or emission of photon by atomic hydrogen

Statement-1: Photon has definite momentum though it has no rest mass. Statement-2: Momentum of photon is due to its energy and therefore it has equivalent mass.
