Answer 1

Describe how light travels from the sky to the viewer's eye. First, light from the sky travels into the concave mirror, which reflects the light to a smaller and flat mirror. Then, the small mirror reflects that light into the telescope's magnifying lens. This lens makes the light reach the viewer's eyes.
