Why does a convex mirror have no focal point?
A convex mirror diverges light rather than converging it, so it does not have a real focal point like a concave mirror. The reflected light appears to be coming from a virtual focal point located behind the mirror. This property makes convex mirrors useful for creating a wider field of view in applications such as side mirrors on vehicles.
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.
Do cameras have concave or convex lenses?
Cameras typically use convex lenses to focus light onto the image sensor or film. Concave lenses are not commonly used in cameras because they cause light to diverge rather than converge, making them unsuitable for image formation.
What happens to the image in a concave mirror when an object is closer to the mirror than one focal length?
When an object is placed closer to a concave mirror than its focal length, the image formed is virtual, upright, and magnified. The image is located behind the mirror, and the rays of light appear to diverge from a point behind the mirror rather than converging at a real focal point.
What is the difference between a concave and convex lens?
Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.

Is concave a shape?
Concave is not a shape, it is the term for when two lines meet facing inwards, rather than outwards (outwards is known as convex)

What is a disorder when the nails grow concave rather than convex?
Aside from the shape of the free edge, what is the difference between the oval-shape nail and the round-shape nail?
What is the effect when light passes through a concave lens?
When light passes through a concave lens, it diverges outward. This causes the light rays to spread apart rather than converging at a single focal point as with a convex lens. As a result, the image formed by a concave lens is virtual, upright, and reduced in size.
What type of lens is used in the eyepiece for reflecting telescopes?
A radio telescope is a reflecting telescope, and uses a mirror rather than a lens. Since radio waves are so much longer than light waves, the 'mirror' of a radio telescope is the 'dish' reflector that focuses radio waves onto its antenna, located at the prime focus of the dish.
What is ampliftion?
Amplification, if that is what you question, is the making a observed item larger. This could occur in an electronic circuit; or it could occur using a convex lens or a concave mirror. In a rather specialized application, PCR is a chemical and physical process by which a minute portion of DNA may be amplified. [Polymerase Chain Reaction]. Though in this case, the starting material is actually replicated.
What is a hyperbolic mirror?
A hyperbolic mirror is a type of mirror with a surface that curves outward like a saddle rather than inward like a regular concave mirror. It is often used in telescopes and satellite dishes to focus or reflect light to a specific point. The unique curve of a hyperbolic mirror helps to reduce spherical aberration and produce sharper images.
