Explain about refracting telescopes, Physics

Assignment Help:

Refracting telescopes, if uncorrected, suffer from chromatic aberration. 

Chromatic aberration occurs because:

a)  red light is focused more strongly than blue light

b)  blue light is focused more strongly than red light

c)  the outer light rays are focused more strongly than the central rays,

d)  the central light rays are focused more strongly than the outer rays.

 

Ans- Blue light is focused more strongly than red light
