The maximum kinetic energy and work function are 2 eV and 8 eV, respectively. What is the energy of the incident radiation?
A
10 eV
B
16 eV
C
20 eV
D
6 eV
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
Einstein’s photoelectric equation: E = K\(_{\max}\) + \(\phi\)
E = 2 eV + 8 eV = 10 eV
