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
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.
