What are the characteristics of concave and convex lens?
A concave lens is thinner in the middle and thicker at the edges. A convex lens is thicker in the middle and thinner at the edges. Used in the camera, focus sunlight, overhead projector, projector microscope, simple telescope, magnifying glasses, etc. It is also used for the correction of the problem in long sight.
Which type of image is formed by convex lens?
A convex lens will focus light and make a real and inverted image. The size of the image will depend on the position of the object and lens. concave lens is also called a diverging lens. A concave lens will disperse light and make an image that is always virtual, upright and smaller than the object.
What is the function of a convex lens?
Convex lenses are used in eyeglasses for correcting farsightedness, where the distance between the eye’s lens and retina is too short, as a result of which the focal point lies behind the retina. Eyeglasses with convex lenses increase refraction, and accordingly reduce the focal length.
What are examples of convex lens?

- Eye glasses.
- Flashlights.
- Lasers ( CD, DVD players)

What are the applications of concave and convex lens in daily life?
Concave lenses are used in glasses to correct the nearsightedness or myopia. In lasers, small concave lenses are used to widen the laser beam. Camera manufacturers use concave lenses in combination with convex lenses to improve the quality of photographs.

How are convex mirrors used in everyday life?
Convex mirrors are used inside the buildings, They are also used in making lenses of sunglasses, They are used in the magnifying glass, They are used in securities and they are used in telescopes.
How are convex mirrors used?
These convex mirrors are used for cars because they give an upright image and provide a wider field of view as they are curved outwards. The convex mirror is also used to provide safety for motorists on roads, driveways and in alleys where there is a lack of visibility.
