159 of 200

Question 159 of 200

The stopping potential in the context of photoelectric effect depends on the following property of incident electromagnetic radiation:

Show answer and solution

Answer: (D) Frequency

According to Einstein’s photoelectric equation, stopping potential depends on frequency as
hν−hν∘=eVV=hν−hν∘eh\nu -h{\nu }_{^{\circ}}=eV V=\dfrac{h\nu -h{\nu }_{^{\circ}}}{e}
Hence stopping potential depends on frequency.
