PHXII11:DUAL NATURE OF RADIATION AND MATTER

357803 The process of photoelectric emission depends on

1 Temperature of incident light
2 Nature of surface
3 Speed of emitted photo electrons
4 Speed of the incident light
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357804 A nonmonochromic light is used in an experiment on photoelectric effect. The stopping potential

1 Is related to the mean wavelength
2 Is related to the longest wavelength
3 Is related to the shortest wavelength
4 Is not related to the wavelength
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357805 If the work function of a metal is ' \(\phi\) ' and the frequency of the incident light is ' \(v\) ', there is no emission of photoelectron if

1 \(v=\dfrac{\phi}{h}\)
2 \(v < \dfrac{\phi}{h}\)
3 \(v \geq \dfrac{\phi}{h}\)
4 \(v>\dfrac{\phi}{h}\)
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357806 In a photoelectric effect experiment, a light of frequency 1.5 times the threshold frequency is made to fall on the surface of photo sensitive material. Now if the frequency is halved and intensity is doubled, the number of photo electrons emitted will be

1 halved
2 quadrupled
3 Zero
4 doubled
