Assertion (A): A stick is dipped in water in a slanting position. If observed sideways, the stick appears short and bent at the surface of water. Reason (R): A light coming from the stick undergoes scattering from water molecules giving the stick a short and bent appearance.
✓ Correct answer: c) A is true but R is false
ExplanationAssertion (A) is true: When a stick is dipped in water at a slanting position and observed from the side, the stick appears short and bent at the water’s surface.This happens because of refraction, where light rays change direction when they pass from water (denser medium) to air (rarer medium).Refraction is the bending of light as it passes from one medium to another medium with a different refractive index.Reason (R) is false: The reason given in the statement refers to scattering of light, which is incorrect in this context.The phenomenon responsible for the apparent bending and shortening of the stick is refraction, not scattering.Scattering involves the redirection of light by particles in the medium and is unrelated to the bending of the stick’s image.Direction: The following item consists of two statements, one labeled as the Assertion (A) and the other as Reason (R).You have to answer this item using the code given below.(2001) 263
