SATHEE: Optics Question 432

Optics Question 432

Question: The angular resolution of a 10 cm diameter telescope at a wavelength of 5000 Å is of the order

[CBSE PMT 2005]

Options:

A) $10^{6} r a d$

B) $10^{- 2} r a d$

C) $10^{- 4} r a d$

D) $10^{- 6} r a d$

Show Answer

Answer:

Correct Answer: D

Solution:

Angular resolution $d θ = \frac{1.22 λ}{a}$

$= \frac{1.22 \times 5000 \times 10 \times 10^{- 10}}{10 \times 10^{- 2}}$

$= 6.1 \times 10^{- 6} r a d$ .
