Space telescope A has a diameter of 2.4 metres;space telescope B has a diameter of 6.5 metres.If they take pictures with the same wavelength of light,which telescope will be better able to make separate images of two stars close together on the sky?
A)telescope A
B)telescope B
C)Neither one; if they work at the same wavelength, they will give the same results.
D)Neither one; even in space, telescopes cannot separate objects that are near each other.
