Question

How do refracting telescopes magnify a far away image?

A.
by directing light beams to meet at a focal point
B.
by absorbing light beams’ wavelengths
C.
by forcing light beams to change direction
D.
by measuring light beams’ velocity

Answer 1

My best guess would be C. By forcing light beams to change direction. I know that “refraction” is the bending of a ray when it passes at an angle from one medium into another in which its speed is different.

Answer 2

the answer is (by directing light beams to meet a focal point)

which is answer (A)
