When wavelength of light used in optical instruments A and B are 4500 Å and 6000 Å respectively, the ratio of resolving power of A to B will be

Options

  1. A16:9
  2. B7:1
  3. C9:16
  4. D4:3

Correct answer

D. 4:3

Step-by-step solution

(D) Resolving power of an optical instrument 1 Resolving power at ₁ Resolving power at ₂ = ₁ ₂ [ . Limit of resolution . 1 resolving power ] Ratio of resolving power = 5000 4000 = 5 4 =5: 4
