What are the uses of convex and concave mirrors?
A convex mirror is used for:- A spotlight..... the light in right in the middle and the convex mirror is behind it so the light that shines back ward's hits the mirror and reflect's back and bends into a focal point. A concave mirror is used for:- Dentist mirror.... to magnify a potion's teeth. They are also used in car light's but is very hard to explain. The first answer above relates to a concave mirror.
Do Light Rays converge or diverge?
Light rays converge as well as diverge. it depends upon the type of lens or mirror you pass it through. A concave lens or a convex mirror diverges the light whereas a convex lens or a concave mirror converges the light rays!
Why is concave mirror preferred to convex mirror in solar cookers?
Concave mirrors are preferred in solar cookers because they can focus sunlight onto a single point, creating high temperatures for cooking. This concentrated heat allows for faster cooking times and more efficient use of solar energy. Convex mirrors, on the other hand, would scatter the sunlight rather than concentrating it.
How does a parabolic concave mirror reflect light differently compared to other types of mirrors?
A parabolic concave mirror reflects light differently than other mirrors because it focuses incoming light rays to a single point called the focal point. This results in a sharper and more concentrated reflection compared to flat or convex mirrors, which disperse light in different directions.
Why is the focal length negative for a convex mirror?
The focal length is negative for a convex mirror because the light rays do not actually converge at a single point in front of the mirror. Instead, they appear to diverge from a virtual focal point behind the mirror.
Which of the mirrors depicted above is a single concave mirror?
I'm unable to view images or diagrams, so I can't identify which mirror is a single concave mirror based on your description. However, a single concave mirror is characterized by its inwardly curved reflective surface. If you can provide descriptions of the mirrors, I can help you determine which one is the concave mirror.

What would be the equivalent single-mirror diameter of a telescope constructed from two serparate 11 m mirrors?
To find the equivalent single-mirror diameter, you would add the individual mirror diameters and then take the square root. So for two 11m mirrors, the equivalent single-mirror diameter would be √(11m + 11m)^2 = √(242) ≈ 15.56 meters.
What is converging mirror?
A converging mirror is a type of mirror that bulges outward and curves inward, also known as a concave mirror. These mirrors are curved inward and can converge light rays to a single focal point. They are commonly used in telescopes, microscopes, and makeup mirrors.
Differentiate concave mirror from the convex mirror?
A concave mirror curves inward and can focus light rays to a single point, called the focal point. It can produce real or virtual images depending on the object's distance from the mirror. On the other hand, a convex mirror curves outward and always produces virtual, upright, and diminished images.
What is formed by divergent rays?
Divergent rays are lines that spread apart from a common point. When these rays originate from a single source and continue to diverge, they form a virtual image, typically when dealing with lenses or mirrors. In optics, this phenomenon is often observed with concave mirrors and convex lenses, where the rays appear to emanate from a point behind the lens or mirror.
How and why convex mirrors are used as vigilance mirrors in departmental stores?
Convex mirrors are used as vigilance mirrors in departmental stores because they provide a wide field of view, allowing security personnel to monitor large areas with a single glance. Their curved surface enables them to reflect light from a broader angle, which helps in spotting potential shoplifters or suspicious activities. Additionally, the images reflected in convex mirrors appear smaller and more distant, making it easier to see more of the store environment. This enhances safety and security for both customers and staff.
What telescope was the first to use many mirrors in a honeycomb patter to avoid the difficulties associated with large mirrors?
The Multiple Mirror Telescope (MMT) was the first telescope to use a honeycomb pattern of smaller mirrors to create the effect of a larger mirror. This design helped to minimize some of the difficulties associated with manufacturing and maintaining large, single-piece mirrors.
