In the type of telescope where light follows the path from the primary mirror to the secondary mirror to the eyepiece and then to the eye, it is a reflecting telescope. Reflecting telescopes use mirrors to gather and focus light instead of lenses.
Here's how light travels in a reflecting telescope:
1. Light enters the telescope and gets collected by the primary mirror.
2. The primary mirror reflects the light to the secondary mirror.
3. The secondary mirror then reflects the light to the eyepiece.
4. Finally, the eyepiece focuses the light and allows you to see the magnified image through your eye.
Reflecting telescopes are known for their ability to gather a lot of light, which makes them great for observing faint objects in the sky like distant galaxies and nebulae. They are also popular for their relatively simple design compared to refracting telescopes, which use lenses instead of mirrors.
