Three examples from the live 100-question bank. Answers appear after attempting them in practice mode.
Example 1 · difficulty 1/5
In a photoelectric experiment, monochromatic light of frequency greater than the threshold frequency falls on a metal plate. If the intensity of this light is doubled while its frequency is kept unchanged, then:
- A. the saturation photocurrent doubles but the stopping potential remains unchanged
- B. the stopping potential doubles but the saturation photocurrent remains unchanged
- C. both the saturation photocurrent and the stopping potential double
- D. the saturation photocurrent doubles but the stopping potential is halved
Example 2 · difficulty 2/5
Light of wavelength 400 nm falls on a metal whose work function is 1.9 eV. Taking hc = 1240 eV nm, the magnitude of the stopping potential needed to just stop the fastest photoelectrons is:
- A. 0.8 V
- B. 1.9 V
- C. 1.2 V
- D. 3.1 V
Example 3 · difficulty 2/5
An electron and a proton have the same de Broglie wavelength. The ratio of the kinetic energy of the electron to that of the proton is:
- A. 1
- B. mₚ/mₑ
- C. mₑ/mₚ
- D. √(mₚ/mₑ)
