* Real Images: Real images are formed when light rays actually converge at a point. This means you can project the image onto a screen.
* Telescopes: Telescopes use lenses or mirrors to focus light from distant objects. This focusing action creates a real image at the focal point of the objective lens or mirror.
How it works:
1. Objective lens/mirror: This primary lens or mirror gathers light from a distant object and focuses it.
2. Real Image Formation: The light rays converge at a point called the focal point, creating a real image.
3. Eyepiece: The eyepiece then acts like a magnifying glass, further enlarging the real image and allowing you to see it.
Note: While the real image formed by a telescope is inverted (upside down), we see it upright through the eyepiece. This is because the eyepiece itself acts like a magnifying glass, flipping the image.
