Question

If the binding energy of electrons in a metal is 250kJ/mol, what is threshold frequency of striking photons​?

Answer 1

Binding energy of electron =250KJ/mol

Binding energy of one electron =250×1036.023×1023J

⇒4.15×10−19J

Binding energy =hv0

v0 is threshold frequency

4.15×10−19=6.625×10−34×v0

v0=6×1014sec−1

Answer 2

hey here is your answer

Binding energy of electron =250KJ/mol

Binding energy of electron =250KJ/molBinding energy of one electron =250×1036.023×1023J

Binding energy of electron =250KJ/molBinding energy of one electron =250×1036.023×1023J⇒4.15×10−19J

Binding energy of electron =250KJ/molBinding energy of one electron =250×1036.023×1023J⇒4.15×10−19JBinding energy =hv0
