# image formed by convex lens

Question 3 The image formed by convex lens is seen to be real,inverted and highly magnified.What is the position of the object? So here we can say that the images formed can be of a variety of types. When a ray, parallel to the principal axis strikes concave or convex lenses, the reflected ray passes through a focus on the principal axis. When an object is placed at infinity, the real image is formed at the focus. When the object is placed between the focus F and optical centre C. When an object is placed between the principal focus and optical centre of a convex lens, then a parallel ray of light AO passes through the focus after refraction along the direction OX. When the object is placed at the centre of curvature of a lens then a ray of light AO which is parallel to the principal axis after refraction pass through the focus F along the direction OF. At the focus F 6. When an object is at the center of curvature, the real image is formed at the other center of curvature. When an object is placed at the focus, a real image is formed at infinity. Important Solutions 2858. We will now discuss the formation of different types of images by a convex lens when the object is placed, 1. A camera or human eye. When the object is placed at infinity, the two rays AO and BD running parallel to the principal axis get refracted at point O and D respectively and intersect each other at the principal focus. These two refracted light rays intersect each other at point A’, between the focus F and centre of curvature 2F on the other side of the lens. 1)A ray parallel to principal axis. When an object is placed at a finite distance from the lens, a virtual image is formed between the pole and the focus of the convex lens. Image formation by Concave Lens: while the other ray AC pass through the optical centre and goes straight without any deviation along the direction CY. Perhaps you noticed that there is a definite relationship between the image characteristics and the location where an object placed in front of a double convex lens. When the object is placed between the focus F and the centre of curvature 2F. Question Bank Solutions 24558. The properties of the image formed by a plane mirror Table of Summary of Image Formed by a Convex Lens. Your email address will not be published. so, the image A’B’ formed in this case is at the centre of curvature, of same size as the object, real and inverted. When an object is placed at the principal focus F, a ray of light AO which is parallel to principal axis after refraction pass through the focus along the direction OX. Images formed by Convex Lens . When an object is placed at infinity, a virtual image is formed at the focus. A ray of light … When a ray strikes concave or convex lenses obliquely at its pole, it continues to follow its path. What should be the position of an object in order to make its highly diminished image at principal focus of a convex lens. At 2F 4. The size of the image is much smaller than that of the object. Image formed by a convex lens when the object is placed at infinity. lens depends on the lens used and the distance from the object to the lens. Also the image formed is erect and highly enlarged. When an object is placed behind the center of curvature, the real image is formed between the center of curvature and focus. As you bring the object more close to the lens, we get the image all the more enlarged. Hence, the image A’B’ formed in this case is a virtual image which is formed on the same side of the lens behind the object. The size of the image is smaller than that of the object. So, lenses formed by binding two spherical surfaces bulging outward are known as convex lenses while the lenses formed by binding two spherical surfaces such that they are curved inward are known as concave lenses.
