Answer:
Angular spread,
Explanation:
It is given that,
Wavelength of the light,
Diameter of the telescope, D = 5.08 m
The minimum angular spread is given by :
So, the minimum angular spread of the beam is . Hence, this is the required solution.
I need to know which ones are physical or chemical changes.
