4. The threshold frequency of a metal is 4 × 10 14 s –1 . The minimum energy which photons must possess to produce photoelectric effect with the metal is (h = 6.6 × 10 –34 Js)

Question

4. The threshold frequency of a metal is 4 &times; 10 14 s &ndash;1 . The minimum energy which photons must possess to produce photoelectric effect with the metal is (h = 6.6 &times; 10 &ndash;34 Js)

Khandavalli Satya Srikanth · Answer

Minimum energy required to produce photoelectric effect is threshold energy which is given by E=h*frequency E=(6.6*10^-34)*(4*10^14)=2.64*10 -19 J
