Light of wavelength 500 nm is incident on a metal with work function 2.28 eV. The de Broglie wavelength of the emitted electron is:
- \(\leq 2.8 \times 10^{-12} \mathrm{~m}\)
- \(<2.8 \times 10^{-11} \mathrm{~m}\)
- \(<2.8 \times 10^{-9} \mathrm{~m}\)
- \(\geq 2.8 \times 10^{-9} \mathrm{~m}\)
Answer
(C) <2.8 10^ -9 ~m
