Answer:
work function = 6 × 10^(-19) J
Explanation:
work function = h c ÷ wavelength
{ h = Planck's constant
c = speed of light in vaccum
wavelength = threshold wavelength }
work function = 6.6 × 10^(-34) × 3×10⁸ ÷ { 330×10^(-9) }
work function = 0.06 × 10^(-17) J
work function = 6 × 10^(-19) J

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
