When photons of energy 4.25 eV strike the surface of metal A, the ejected photoelectrons have maximum kinetic energy, TA eV and de Broglie wavelength λA. The maximum kinetic energy of photoelectrons liberated from another metal B by photons of energy 4.70 eV is TB = (TA- 1.50) eV. If the de Broglie wavelength of these photoelectrons is λB = 2λA, then
  • a)
    The work function of A is 2.25 eV
  • b)
    The work function of B is 4.20 eV
  • c)
    TA = 2.00 eV
  • d)
    TB = 2.75 eV
Correct answer is option 'A,B,C'. Can you explain this answer?
Verified Answer
When photons of energy 4.25 eV strike the surface of metal A, the ejec...
 For metal A
4.25 = WA + TA           ...(i)
For metal B
4.7 = (TA – 1.5) + WB ...(iii)
Dividing equation (iv) by (ii),
[∵ λ B = 2λA given]
⇒ 4TA – 6 =TA ⇒ TA = 2 eV
From (i), WA = 2.25 eV
From (iii), WB = 4.2 eV
Also TB = TA – 1.5 ⇒ TB = 0.5eV
