Differentiate between lenses & images
Dear Student,
Lenses are the optical devices used to transmit and refract light through them and the image formed by them are used for further purposes.
Generally there are two spherical lenses i.e. concave and convex lenses.
Images are of two types one is real and the other is virtual. Real image can be traced on a screen and formed behind the lens whereas virtual cannot be trace on a screen and always formed in front of the lens.
Convex lens forms both virtual and real images. The size of a virtual image is larger than the size of the object, whereas the size of a real image may be the same, smaller, or larger than that of the object, depending on the distance of the object from the lens.
Whereas, A concave lens forms virtual images of a smaller size. The images are erect and are formed in front of the lens.
