WebThe energy and threshold frequency is related by equation E=hν, where h is the plank’s constant and ν is the threshold frequency. Substituting the value of ν and plank’s constant, we get E= (6.626×10 -34 ) (4.83×10 14) E=3.20×10 -19 The binding energy per metal atom can be obtained by multiplying the energy by the Avogadro number. Expressed as WebAug 31, 2024 · Let us use the relation between the frequency and the wavelength of light, i.e. ν=cλ. When the light wave has threshold frequency, its wavelength is called threshold …
