PHXII11:DUAL NATURE OF RADIATION AND MATTER

357653 Photons with energy \(4 {eV}\) are incident on a cathode \({C}\) in a photoelectric cell. The maximum energy of emitted photoelectrons is \(2 \,{eV}\). When photons of energy \(6 \,{eV}\) are incident on \({C}\) and no photoelectrons reaches the anode \({A}\), then the stopping potential is

1 \(1\,V\)
2 \(6\,V\)
3 \(4\,V\)
4 \(2\,V\)

357654 The curve drawn between velocity and frequency of photon in vacuum will be a

1 Straight line parallel to frequency axis
2 Straight line parallel to velocity axis
3 Straight line passing through origin and making an angle of \(45^{\circ}\) with frequency axis
4 Hyperbola
PHXII11:DUAL NATURE OF RADIATION AND MATTER

357655 According to Einstein's photoelectric equation, the graph of \(K.E\). of the photoelectron emitted from the metal versus the frequency of the incident radiation gives a straight line graph, whose slope

1 Depends on the intensity of the incident radiation
2 Depends on the nature of the metal and also on the intensity of incident radiation
3 Is same for all metals and independent of the intensity of the incident radiation
4 Depends on the nature of the metal

357656 When a monochromatic source of light is at a distance of \(0.2\;m\) from a photoelectric cell, the cut-off voltage and the saturation current are respectively \(0.6\;V\) and \(18\;ma\). If the same source is placed \(0.6\;m\) away from the cell, then:

1 The stopping potential will be \(0.2\;V\)
2 The stopping potential will be \(1.8\;V\)
3 The saturation current will be \(0.6\;mA\)
