Concave mirrors used to focus light on a point, such as in a solar collector, would be in the shape of either a Hyperbolic or Parabolic section. The reason for the xxxxbolic section is that they both have focal points (foci?). any light coming into the mirror at any angle is reflected to this focal point. Think of using a magnifying glass to burn ants... you need to move the glass higher or lower to the ground until you get that bright dot of concentrated light/heat and then you can burn ants. The small white dot of light/heat is the focal point of you magnifying glass. Hope that helps..

Does a Concave mirror bend light outwards or inwards?
A concave mirror bends light inwards towards a central focal point. This type of mirror can focus light rays to create a real or virtual image, depending on the distance between the object and the mirror.
How does a concave mirror affect light?
A concave mirror will tend to "focus" light to some degree, depending on the curvature of the mirror. A parabolic mirror will bring reflected light to a sharp focus, and telescopes use this type of curve for the shape of their reflective surface. And for exactly the reasons you think they do. Want links? You got 'em....
Why inner curved surface is known as Concave mirror?
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
Why is a concave mirror used as reflector in torch light?
A concave mirror is used as a reflector in a torch light because it can focus light rays emitted from a point source, such as a bulb, into a parallel beam. This focusing ability enhances the intensity and directionality of the light, allowing for a more concentrated and powerful illumination. Additionally, the shape of the concave mirror ensures that the light is directed forward, maximizing the efficiency of the torch light.
Why is concave mirror used in street lights?
bcause when light source placed at focus of the mirror, after flashing the light form the source to the mirror after reflection a straight parallel beam of light emerges which makes the street bright
Can a concave mirror focus light?
Yes, a concave mirror can focus light. When light rays reflect off a concave mirror, they can come together at a single point known as the focal point. This can create a focused image.
Which spherical mirror has a virtual focus-concave or convex?
A concave mirror has a virtual focus. This is because the rays of light that are incident on a concave mirror are reflected and appear to diverge from a point behind the mirror, creating a virtual focus.
Why a side mirror is never a concave mirror?
A concave mirror would focus the light back towards the focal point of the mirror. You would not be able to use the mirror effectively with a concave.
When light strikes the large concave mirror of a reflecting telescope where is the light focus?
In front of the mirror
Is a street light mirror concave or convex?
A street light mirror is typically concave. Concave mirrors are used in street lights to reflect light downwards and maximize illumination on the street below. The curved surface of the concave mirror helps to focus the light in a specific direction.
Which factor most influence image produce by concave mirror?
A concave mirror cause light rays to converge at the focus
Does a flashlight use a concave mirror or convex mirror?
It uses a concave mirror in order for the light to be concentrated to point forward.
What kind of mirror do you have if reflected rays of light pass through the principle focus when light hits a mirror parallel to the principle axis?
The mirror is a concave mirror. This behavior is a property of concave mirrors, where parallel rays of light are reflected and converge at the principal focus after reflection.
Is search light mirror concave or convex?
concave
Define the principal focus of a concave mirror?
The principal focus of a concave mirror is the specific point where parallel rays of light converge or appear to diverge after being reflected. It is located halfway between the mirror's surface and its center of curvature.
What mirror causes light rays to converge?
concave mirror and convex lens can be used to focus light rays. they are also called converging mirror and lens respectively. They focus the light at a distance of its focal length.
What are the uses of a concave mirror of a microscope?
A concave mirror in a microscope is used to reflect and focus light onto the specimen being observed. It helps increase the amount of light that reaches the specimen, resulting in a brighter image. Additionally, the concave mirror helps in magnifying the image by reflecting light rays at an angle towards the objective lens.
