Photoelectric Effect Theory

The photoelectric effect demonstrates that light can eject electrons from a metal surface when the light's frequency exceeds the metal's threshold frequency.

Key Equations

Cut-off Voltage: eV₀ = h(ν - ν₀) = K_max

Where:

• V₀ = cut-off voltage
• ν = frequency of incident light
• ν₀ = threshold frequency of metal
• h = Planck's constant (6.626 × 10⁻³⁴ J·s)
• e = electron charge (1.6 × 10⁻¹⁹ C)
• K_max = maximum kinetic energy of ejected electrons

Current Simulation Results

Threshold Frequency (ν₀): 3.3 ×10¹⁴ Hz

Incident Frequency (ν): 8.2 ×10¹⁴ Hz

Cut-off Voltage (V₀): 2.03 V

Emission Status: ACTIVE (ν > ν₀)
