Solution - The Resolving Power of a Telescope Depends Upon the - Resolving Power of a Microscope and Telescope

The numerical aperture of objective of a microscope is 0.12. The limit of resolution, when light of wavelength 6000A is used to view an object is.......................

1. 0.25 * 10^-7m
2. 2.5 * 10^-7m
3. 25 * 10^-7m
4. 250 * 10^-7m

If numerical aperture of a microscope is increased, then its .......................................... .

1. resolving power decreases
2. limit of resolution decreases
3. resolving power remains constant
4. limit of resolution increases.

If 'a' is the aperture of telescope and A. is the wavelength of light then resolving power of telescope is .............

a) `lambda/(1.22a)`

b) `(1.22a)/lambda`

c) `(1.22 lambda)/a`

d) `a/(1.22lambda)`

The resolving power of telescope of aperture 100 cm for light of wavelength 5.5 x 10^-7 m

(A) 0.149 x 10⁺⁷

(B) 1.49 x 10⁺⁷

(C) 14.9 x 10⁺⁷

(D) 149 x 10⁺⁷
