⚠️ Common Exam Traps & Conceptual Pitfalls

Students often assume the stopping potential reflects the average or longest wavelength of a non‑monochromatic beam, but it is set by the maximum kinetic energy of the emitted electrons, which comes from the highest‑frequency (shortest‑wavelength) photons. Always identify the photon with the greatest $hf$ when relating $V_{stop}=\frac{hf_{max}-\phi}{e}$.

A non-monochromatic light is used in an experiment on photoelectric effect. The stopping potential

Multiple Choice Options

  • A is related to the mean wavelength
  • B is related to the longest wavelength
  • C is related to the shortest wavelength
  • D is not related to the wavelength

Step-by-Step Verified Solution

**Answer:** (c) is related to the shortest wavelength. **Step-by-Step Explanation:** Stopping potential is determined by the maximum kinetic energy, which comes from the shortest wavelength (highest frequency) photons.
