If the binding energy of electrons in a metal is 250 kJ `"mol"^(-1)` , what is the threshold frequency of the striking photons ?

The binding energy of electron in a metal is 193 kJ mol^(-1) .Find the threshold frequency of the metal

The binding energy of electron in a metal is 193 kJ mol^(-1) .Find the threshold frequancy of the metal

de-Broglie proposed dual natrue for elecrton by putting his famous equation lambda = ( lambda) /( mu) , Later on Heisenberg proposed uncertiainty principle as . Deltap.Deltaxle(h)/(2)(h=(h)/(2pi)) . On the contray particel natrue of electron wa estabilshed on the basis fo photoelectric effect . When a photon strikes the metal suface it given up its energy to the electro . Part of this enrgy ( say W) is used by the electrons to escpe form the metal and the remaining imparts he kinetc enrgy (1//2 mu^2) to photoeleton . The potential applied on the surface to reduce the velocity fo photoelecton to zero is known as stoppong potential The binding eenrgy fo electron in a metal is 250 kJ mol^(-1) . The threshold frequency of metal is :

Threshold wavelength for a metal is 6000 A^@ . What is the threshold frequency?
