We are given a concave mirror. An object of size 7.0 cm is placed at 27 cm in front of a concave mirror of focal length 18 cm. It is found that CB' = 3.3 cm and A'B' = 0.7 cm. If the equation shows a negative image distance, then the image is a virtual image on the same side of the lens as the object. A concave lens of focal length 15 cm forms an image 10 cm from the lens. Your email address will not be published. An object 5.0 cm in length is placed at a distance of 20 cm in front of a convex mirror of radius of curvature 30 cm. Find the position of the image, its nature and size. It can form both real and virtual images depending on where the light is coming from. Hi I am Girish Chandra.Welcome to my youtube channel Chandra Mathematics. A virtual and erect image of height 2.2 cm is formed behind the mirror (because v is positive) at a distance of 8.6 cm from the mirror. A simple kind of these lenses can focus light into an image, but that image won’t be of a high quality. (iii) Mark two foci F and F' on two sides of the lens, each at a distance of 2 cm from the lens. As the distances given in the question are large, so we choose a scale of 1: 5, i.e., 1 cm represents 5 cm. Therefore, on this scale 5 cm high object, object distance of 25 cm and focal length of 10 cm can be represented by 1 cm high, 5 cm and 2 cm lines respectively. (v) Draw a line AD, parallel to principal axis. So the most common use of the lens is that it helps us to see. Converging lens means a convex lens. The lens in the human eyes is the prime example. Read about the convex lens along with its use and difference between the concave and convex lens. Class 1 - 3; Class 4 - 5; Class 6 - 10; Class 11 - 12; CBSE.
