The angular resolution of a 10 ~cm diameter telescope at a wavelength of 5000 Å is of the order of:
Options
- A10^6 rad
- B10⁻² rad
- C10⁻⁴ rad
- D10⁻⁶ rad
Correct answer
D. 10⁻⁶ rad
Step-by-step solution
Here R P .= 1 aligned & Angular resolution = 1.22 D &= 1.22 5000 10⁻¹⁰ 0.1 &=6.10 10⁻⁶ & 10⁻⁶ aligned
