Question

Kinetic energy of photoelectrons is independent of ...........of incident radiation.

• A. Frequency
• B. Wavelength
• C. Wave number
• D. Intensity

Answer 1

Answer: (D)

Intensity

Answer 2

KE = hn – hn₀ = h (n – n₀)

= hc $\left( \frac{1}{\lambda}–\frac{1}{\lambda_{0}} \right)$

= hc $(\bar{\nu}–{\bar{\nu}}_{0})$
