Answer: A. Larry must have grabbed a concave lens since the legs look smaller.
Explanation:
I'm not sure. I did some research and it seems that this is the correct one because, universe today.com said; "A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia)." and passmyexams.co.uk said; "Convex lenses are thicker at the middle. Rays of light that pass through the lens are brought closer together (they converge). A convex lens is a converging lens. Â When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. Â The distance between the principal focus and the centre of the lens is called the focal length." and so, this lead me to believe that the answer is; A. Larry must have grabbed a concave lens since the legs look smaller.
