Question

an object is placed 50 cm from a lens produces a virtual image at a distance of 10cm in front of the lens draw a diagram to show the formation of image calculate focal length of the lens and magnification produces ​

Answer 1

Explanation:

An object placed 50 cm from a lens produces a virtual image at a distance of 10 cm in front of the lens. Thus, the magnification produced by this concave lens is +0.2. Since the value of magnification is less than 1 (its is 0.2), therefore, the image is smaller than the object (or diminished).
