What to Focus On
- Photoelectric effect: emission of electrons when light of suitable frequency falls on a metal surface.
- Threshold frequency (ν₀): minimum frequency required to eject electrons.
- Photoelectrons are emitted instantly, even for dim light.
- Saturation current: maximum current when all photoelectrons reach the anode.
- Stopping potential (V₀): minimum reverse voltage to stop photoelectrons.
- eV₀ = (1/2)mv_max²: kinetic energy of fastest electron equals work done against stopping potential.
- Light consists of photons, each with energy hν.
- Einstein’s equation: hν = φ₀ + K_max.
- K_max = h(ν − ν₀): kinetic energy depends on frequency, not intensity.
Common Mistakes to Avoid
Photoelectric effect depends on intensity of light, not frequency.
Increasing light intensity increases the kinetic energy of photoelectrons.
Photoelectric emission is not instantaneous if light is dim.
Memory Tips
Photoelectric effect definition: Emission of electrons when light of sufficient frequency hits a metal surface.
Einstein’s photoelectric equation: \( h u = \phi_0 + K_{\max} \)
Threshold frequency (ν₀): Minimum frequency of light needed to eject electrons.
Stopping potential (V₀): Minimum retarding voltage to stop photoelectrons.
