What are the uses of convex and concave mirrors?
Convex mirrors are commonly used in vehicles to provide a wider field of view. They are also used in security cameras to create a larger area of surveillance. Concave mirrors are used in reflecting telescopes to gather and focus light onto a single point for clearer images.
Do Light Rays converge or diverge?
Light rays can converge or diverge based on the type of lens or mirror they pass through. Converging lenses and concave mirrors cause light rays to converge, focusing them at a single point known as the focal point. Diverging lenses and convex mirrors cause light rays to diverge, spreading them out.
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.
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 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 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.
What does concave mirror mean in science?
A concave mirror is a curved mirror where the reflective surface bulges inward. It can converge light rays to a single focal point, producing real or virtual images depending on the object distance. Concave mirrors are commonly used in optical devices like telescopes and shaving mirrors.
Will converge light rays to a single focal point on the specimen?
A convex lens will converge light rays to a single focal point on the specimen. This property makes convex lenses useful in magnifying and focusing light in microscopes and other optical instruments.
Would the mirror equation work for plane mirrors?
No, it will not, this is because a plane mirror has no focal point. It's rays never converge at a single point like a concave mirror, and therefore it has no focal point The mirror equation is 1/f=1/di + 1/do, where f is the focal point, di is the distance of the image from the mirror, and do is the distance of the reflected object from the mirror. Since focal point is required for the equation, it can't work. Hope this helps.
Why is concave mirror called converging mirror?
A concave mirror is called a converging mirror because it converges or focuses light rays that are parallel to its principal axis at a single point called the focal point. This property makes concave mirrors useful for creating focused images.
Do concave mirrors reflect sharp images?
Yes, concave mirrors can reflect sharp images. When an object is placed appropriately in front of a concave mirror (closer than the mirror's focal point), the mirror can focus light rays to form a sharp image. This image will be right-side up or upside down, depending on the distance between the object and the mirror.
