Mention 3 practical application of curved mirror

Here are three practical applications of curved mirrors:

1. Car headlights and searchlights: Parabolic mirrors are used as reflectors in car headlights and searchlights. They reflect light from a bulb placed at the focal point into a parallel beam, allowing the light to travel long distances.

2. Telescopes: Reflecting telescopes use large concave mirrors to gather and focus light from distant celestial objects. The curved surface allows for the collection of more light than a simple lens, producing brighter and more detailed images.

3. Dentist's mirror: Dentists use small, slightly curved (usually convex) mirrors to get a magnified view of teeth and the inside of the mouth. This allows them to see details that would otherwise be difficult to observe.
