Dual nature of radiation and Matter

142018 Flank and Hertz experiment proves that

1 Light moves in the form of waves as well as particles
2 The electron does not radiate energy, while moving in an orbit
3 The energy states of an atom are quantised
4 The whole of the positive charge of the atom is concentrated in the nucleus

Dual nature of radiation and Matter

142027 In a photoelectric effect experiment, collector plate is placed vertically above the emitter plate. Light is allowed to incident on emitter and saturation photocurrent is recorded. Now parallel electric and magnetic field are applied vertically downwards between the plates. Then

1 The photocurrent will increase
2 The kinetic energy of photoelectrons will decrease
3 The stopping potential will increase
4 The threshold wavelength will increase

Dual nature of radiation and Matter

142033 The stopping potential of the photoelectrons, from a photo cell is

1 inversely proportional to intensity of incident light
2 directly proportional to intensity of incident light
3 inversely proportional to frequency of incident light
4 directly proportional to frequency of incident light

Dual nature of radiation and Matter

142039 As the intensity of incident light increases

1 Photoelectric current increases
2 Photoelectric current decreases
3 Kinetic energy of photoelectron increases
4 Kinetic energy of photoelectron decrease
