A) 2.125 cm
B) 1.525 cm
C) 0.125cm
D) 1.225 cm
Correct Answer: B
Solution :
Key Idea: Resolving power is the ability of lens to measure the angular separation of images that are close together. The resolving power of a lens is limited by diffraction effects. The lens aperture is a hole that is analogous to a two dimensional version of the single slit experiment. For an ideal lens the resolution is \[d=\frac{1.22\lambda \times D}{a}\] \[\therefore \] \[d=\frac{1.22\times 5000\times {{10}^{-10}}\times 50}{2\times {{10}^{-3}}}\] = 1.525 cmYou need to login to perform this action.
