What are the difference between convex lens and concave lens?
A convex lens or converging lens focuses the light rays to a specific point whereas a concave lens or diverging lens diverges the light rays. When these lenses are combined, they produce sharper images. …
What happens when you look through a concave lens?
Photo: A concave lens makes parallel light rays diverge (spread out) so that they appear to come from a point behind the lens—the focal point. The distance from the center of the lens to the focal point is, again, the focal length of the lens.
Is a magnifying glass convex or concave?
A magnifying glass is a convex lens used to make an object appear much larger than it actually is. This works when the object is placed at a distance less than the focal length from the lens.
What kind of lens is used to correct farsightedness?
Do concave lenses always produce smaller images?
Explanation: The Answer is Concave. Concave images make images smaller, they refract the light rays in many directions, causing the original image to shrink. Convex lenses, the other type of diverging lenses, cause the image to be larger, because it concentrates the image in a specific point.
Can we obtain a real enlarged and inverted image by a concave mirror?
We can obtain an enlarged and erect image by a convex mirror. A concave lens always forms a virtual image. We can obtain a real, enlarged and inverted image by a concave mirror.
Which lens can form an erect image?
What is erect image explain?
An erect image, in optics, is one that appears right-side up. An erect image is formed when both rays intersect each other at a certain point. It is an image in which directions are the same as those in the object, in contrast to an inverted image. It is one of the properties of images formed in a plane mirror.
Why we see your erect image in the mirror at home?
It is due to the reason that plane mirrors, the commonly used household mirrors, always form images which are virtual, erect and possess the same size and shape as that of the object. When we lift up our left hand, in the mirror, we see it be our right hand and vice-versa.
