Using Light: Concave Mirrors

The video explains the properties and applications of concave mirrors. It starts with a simple example of seeing one's reflection in a spoon, which acts as a concave mirror. The video then describes how concave mirrors are used in telescopes to gather light from distant objects in space. It explains the principle of light reflection, where parallel light rays are focused at a point, and vice versa. Finally, the video discusses the use of concave mirrors in car headlights and flashlights to create strong, focused beams of light.
