alleryFor photoelectric experiment, plot of KE_max vs frequency ν is:
ACurve
BParabola
CStraight line with slope h, intercept -φ
DHorizontal
Answer & Solution
Correct answer: C. Straight line with slope h, intercept -φ
KE_max = hν - φ. Linear in ν.
Slope = h (Planck constant, universal).
Intercept on ν-axis = ν₀ = φ/h (threshold).
**Different metals:** same slope, different intercept.
