Question

Assume that you have a telescope with an aperture of 1 meter. Compare the telescope’s theoretical resolution when you are observing in the near-infrared region of the spectrum (l 5 1,000 nm) with that when you are observing in the violet region of the spectrum (l 5 400 nm).

Answer 1

A2 = 0.106 A1

Hence, the reolution with lower wavelength is lower.

Step-by-step explanation:

We know that the angular resolution of the telescope is given by

A = lambda/D

where lambda is wavelength and D is aperture diameter

since aperture diameter is constant , therefore

A2 /A1 = lambda2 /lambda1

A2 /A1 = 5400 /51000 =0.106

A2 = 0.106 A1

hence the reolution with lower wavelength is lower
