Answer & Solution
Correct Answer
(A) (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
Step-by-step Solution
Detailed explanation
(A) Einstein's Photoelectric Equation: \( K_{max} = hc/\lambda - \phi \) matches (II) (B) De-Broglie Wavelength: \( \lambda = h/p \) matches (IV) (C) Stopping potential: \( V_0 = K_{max} / e \) matches (I) (D) Threshold wavelength: \( \lambda_{th} = hc/\phi \) matches (III) The…
