If threshold wavelength for ejection of electron from metal is 330nm, then work function f Find an answer to your question If threshold wavelength for ejection of electron from metal is 330nm, then work function for photoelectric emission is

Answer 1

Answer:

Work function is the minimum energy required to eject an electron from the metal surface.

work function=hv°

Threshold frequency=c/^=3×10^8/330×10^-9=1×10^17/11=8^-1

work function=6.626×10^-34×10^17/11=6×10^-19J

Explanation:

Answer 2

As we know,

W = hvo= hc/λo

W = 6.6 × ${10}^{-}$ ³⁴ × 3 × 10⁸/ 330 × ${10}^{-}$ ⁹

W = 6 × ${10}^{-}$ ¹⁹ J
