Question

- A convex lens has a focal length of 20cm. Where should an object be placed in front of
convex lens so as to obtain an image which is real, inverted and same size as the object ? Draw
the ray diagram to show the formation of image in this case.​

Answer 1

Answer:

When an object is placed at the centre of curvature in front of a convex lens, its image is formed at the centre of curvature on the other side of the lens. The image formed is real, inverted, and of the same size as the object. How satisfied are you with the answer?In case of convex lens when an object is placed at centre of curvature, a real, inverted and equal size image is obtained on the other centre of curvatureWhere should an object be placed in front of a convex lens to get a real image of the size of the object? Answer: At twice the focal length, the image formed by the convex lens is real and of the same size as the object.
