Answer:

Light from the sky travels to a large concave mirror, where it reflects onto a small flat mirror. The small mirror reflects the light, sending it to a magnifying lens. The lens is part of the eyepiece, where the magnified light reaches the viewer’s eye.

The speed of light in a vac uum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

I hope my answer has come to your help. God bless you and have a nice day ahead!
