Emission of electrons in photoelectric effect is possible, if

Production of X - ray and emission of electron in photoelectric effect are two opposite phenomena. '' Justify the statement.

Production of X-rays and emissions of electron in photoelectric effect are two opposite phenomena." Justify the statement.

Kinetic energy of electrons emitted in photoelectric effect is

If the wavelength of light in an experiment on photoelectric effect is doubled, (i) the photoelectric emission will not take place (ii) the photoelectric emission may or may not take place (iii) the stopping potential will increase (iv) the stopping potential will decrease

Photoelectric effect was first observed by Hertz. The number of electrons ejected in the photoelectric effect is proportional to_____of light used (frequency, intensity)

The kinetic energy of the ejected electrons in photoelectric effect is

A : The process of photoelecton emission and thermionic emission of electrons is different . R : Photoelectric emission does not depend upon tempereature , whereas thermionic emission is temperature depandent .
