Question

In an experiment with convex lens, an object is placed between the centre of curvature and focal point draw a Ray diagram showing the image in such a case and comment the image ​

Answer 1

Answer:

Explanation:

The image is real and hence is inverted. It is also given that the focal length is cm. (In a concave mirror, is negative). The object should be placed at a distance of cm from the mirror.D – using a lens of longer focal length, when light rays pass through the lens, it will converge to a point further away from the lens. Hence the sharp image will be formed on the school. Alternatively, you can move the screen nearer to the lens such that the position of the screen is at the intersection of the rays.A converging lens will only produce a virtual image if the object is located in front of the focal point. 3. A converging lens is sometimes used as a magnifying glass. f, the focal length, is positive for a concave mirror, and negative for a convex mirror. When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.
