Photoelectric threshold frequency ν₀ = φ/h. If work function doubles, ν₀:

Question

Team JKSSB Mock Tests · Accepted Answer

ν₀ ∝ φ. Double work function ⇒ double threshold frequency. Higher φ requires higher photon energy for emission. Memory tip: 'ν₀ = φ/h; larger φ ⇒ higher frequency needed'. Photoelectric effect relation frequently tested in competitive quantum physics sections.
