Concave mirror
Concave mirrors
A concave mirror is a type of mirror that curves inward, like a bowl. It's also known as a converging mirror because it converges light rays that hit it.
Properties:
1. Converges light rays: Concave mirrors focus light rays to a single point, called the focal point.
2. Forms real images: Concave mirrors can form real images that can be projected onto a screen.
3. Magnifies objects: Concave mirrors can magnify objects when they are placed within the focal length.
Applications:
1. Telescopes: Concave mirrors are used in telescopes to collect and focus light from distant objects.
2. Optical instruments: Concave mirrors are used in optical instruments, such as spectrometers and interferometers.
3. Solar concentrators: Concave mirrors are used to concentrate sunlight onto a small area, increasing the temperature.
4. Shaving mirrors: Concave mirrors are sometimes used as shaving mirrors to provide a magnified view of the face.
How concave mirrors work:
When light rays hit a concave mirror, they are reflected and converge to a single point, the focal point. The distance between the mirror and the focal point is called the focal length.
