Answer:
statements (a), (c), (e), and (f) are true, while statements (b) and (d) are false.
Step-by-step explanation:
Let's analyze each statement:
(a) The greater the frequency of the incident light is, the greater is the stopping potential.
- This statement is true. According to the photoelectric effect equation, the stopping potential is directly proportional to the frequency of the incident light. As the frequency increases, the stopping potential also increases.
(b) The greater the intensity of the incident light is, the greater is the cutoff frequency.
- This statement is false. The cutoff frequency is determined by the work function of the material, and it is not affected by the intensity of the incident light.
(c) The greater the work function of the target material is, the greater is the stopping potential.
- This statement is true. The stopping potential is directly proportional to the work function of the target material. A higher work function requires more energy to overcome, resulting in a greater stopping potential.
(d) The greater the work function of the target material is, the greater is the cutoff frequency.
- This statement is false. The cutoff frequency is solely dependent on the work function of the material and is not influenced by its magnitude.
(e) The greater the frequency of the incident light is, the greater is the maximum kinetic energy of the ejected electrons.
- This statement is true. The maximum kinetic energy of ejected electrons is directly proportional to the frequency of the incident light. Higher-frequency light provides more energy to the electrons, resulting in greater kinetic energy.
(f) The greater the energy of the photons is, the smaller is the stopping potential.
- This statement is true. The stopping potential is inversely proportional to the energy of the incident photons. Higher-energy photons result in a smaller stopping potential.
