A convex lens has power P . It is cut into two halves along its principal axis. Further one piece (out of two halves) is cut into two halves perpendicular to the principal axis as shown in figure. Choose the incorrect option for the reported lens pieces

Options

  1. APower of L₂ is P 2
  2. BPower of L₃ is P 2
  3. CPower of L₁ is P
  4. DPower of L₁ is P 2

Correct answer

D. Power of L₁ is P 2

Step-by-step solution

P₂ 1 ~F =( -1) 2 R Power of L1 P _ L ₁ =( -1) 2 R = P
