Uses of Convex & Concave Mirrors

The size of the image is smaller as compared to that of the object. The light that goes through it concentrates on a point so you can burn things. Each ray is extended backwards to a point of intersection - this point of intersection of all extended reflected rays is the image location of the object. You should see an upside down image of your finger that is slightly in front of the spoon. Similar devices are sold to be attached to ordinary. Note that the center of curvature and the focal point are located on the side of the mirror opposite the object - behind the mirror. Size Convex mirror forms a smaller image as compared to the original size of the object.

At this point the entire image can be filled in. As a result, images formed by these mirrors cannot be projected on a screen, since the image is inside the mirror. Even the field of alternative energy benefits from this type of mirror. Any incident light ray would work as long as it meets up with the mirror.

As with a satellite dish, the energy from the radiation, in this case solar energy, is concentrated within a small space and is thus very efficient at heating food. It can be of two types, i. A mirror is a surface which reflects a clear image. Now you may be wondering if a concave mirror can produce a virtual image like a flat mirror as well. This is why they are useful. Example Concave mirrors used in torch lights and reflecting telescopes etc.

Comparison between Convex and Concave Mirror: Concave Mirror Convex Mirror Structure A concave mirror is a spherical mirror in which the reflecting surface and the center of curvature fall on the same side of the mirror. It depends on two things: where the object is located in front of the mirror and the focal length of the mirror. The image formed by the convex mirror will be always diminished. Pick a point on the top of the object and draw two incident rays traveling towards the mirror. Earlier in this lesson, the following diagram was shown to illustrate the path of light from an object to mirror to an eye.

But what happens when the object is located at F? Today, two types of telescopes are widely used: refractor telescopes, which employ lenses, and reflector telescopes, which have mirrors. The point at which the two rays described above meet is the image point corresponding to the top of the object. Astronomical Telescopes Galileo Galilei invented the first astronomical telescope in 1609, leading to the controversial discovery that Earth revolves around the sun and not vice versa. Concave And Convex Mirrors And Spherical Mirrors What are Spherical Mirrors? The incident ray that begins from the top extremity of the object and passes through the focal point does not meet the mirror. In this case, the image will be inverted i. If the outside of the sphere is silvered such that it can reflect light, then the mirror is said to be convex.

The diagram below shows an object placed in front of a convex mirror. There are also nonspherical mirrors like parabolic reflectors. When light rays diverge after reflection, a virtual image is formed. Such a mirror can focus incoming parallel rays to a much smaller spot than a spherical mirror can. Concave mirrors are also known as a converging mirror since the rays converge after falling on the concave mirror while the convex mirrors are known as diverging mirrors as the rays diverge after falling on the convex mirror.

What are the uses of concave and convex mirrors in our daily life?

Concave lenses are curved inward and when light goes through it diverges or spreads out. As a result, light from the lamp diverges over a large area. Concave Mirrors A concave mirror is a mirror that is curved inward in the middle. If the reflective surface is on the side curved inwards, it is a concave mirror. Although the figure above is that of a concave mirror, the properties remain the same for convex mirrors as well. The unique reflection that is created by a concave mirror makes the device extremely useful in a number of different devices. A concave mirror is used to focus the light.

The mirrors are basically of two types, they are 1. As the observer sights along a line, a ray of light is reflecting off the mirror to the observer's eye. The two rules of reflection are applied in order to determine the location where all reflected rays appear to diverge from which for real images, is also the location where the reflected rays intersect. You can recognize these mirrors easily as the outward bulge is quite evident most of the time. The concentrated beam of sunlight at a point increases the temperature at that point. The derivations of the ray matrices of a convex spherical mirror and a are very similar.

Reflection and Image Formation for Convex Mirrors

Concave mirrors used in torch lights or reflecting telescopes etc. Place arrowheads upon the rays to indicate their direction of travel. A parallel beam of light diverges spreads out after reflection from a convex mirror, since the to the surface differs with each spot on the mirror. Use a straight edge to accurately draw its path. Sometimes referred to as a converging mirror, the concave mirror is made with a surface that bends inward. While the result of the ray diagram image location, size, orientation, and type is different, the same two rays are always drawn. This type of mirror can be handheld or mounted over the dental chair.
