Question

The script shown on the right when seen with different lenses looks different as shown below. Identify the type of lens used in each case. ABC DE F G O (I) Options (A) (C) (D) (1) Concave lens Convex lens Convex lens Concave lens O BC'DEFG (11) Convex lens Convex lens Concave lens Concave lens

Answer 1

The script looks different due to the type of lenses used. The described outcome of the script being smaller and upright indicates a concave or diverging lens was used in both cases.

Step-by-step explanation:

The script appears different when viewed through various lenses because each lens type manipulates light differently. A convex lens, or converging lens, will make light rays intersect and can form both real and virtual images. A real image is inverted and can be larger or smaller than the object, while a virtual image is always upright and cannot be projected, and it's larger than the object if the lens is convex. Conversely, a concave lens causes light rays to diverge and only forms virtual images that are smaller than the object, which is always upright and cannot be projected.

Based on the descriptions given in the question:

• The first case, where 'ABC DE F G' becomes 'O BC'DEFG', suggests that the image is smaller and upright, indicating the use of a diverging lens or a concave lens.
• The second case, where 'ABC DE F G' becomes 'O BC'DEFG', implies the same outcome as the first, suggesting the same lens type was used, which is a concave lens.
