The telescopes, for a given wavelength, the objectives with large aperture are used for

Options

  1. Agreater magnification.
  2. Bgreater resolution.
  3. Creducing lens aberration.
  4. Dease of manufacture.

Correct answer

B. greater resolution.

Step-by-step solution

According to mathematical equation R.P. 1 , telescopes being used in sunlight to observe celestial objects, practically there is no control on wavelength incident ( ) . Hence, using objective lens of large aperture is effective way to increase R.P. of telescope.
