Answer:
The maximum wavelength is 492 nm.
Explanation:
Given that,
Angular separation 
Suppose a telescope with a small circular aperture of diameter 2.0 cm.
We need to calculate the maximum wavelength
Using formula of angular separation
Put the value into the formula
For small angle 
Hence, The maximum wavelength is 492 nm.
Answer:
