\nLet’s match the explanations with the terms:
\nA. Colour of an opaque object: Opaque objects get their colour by absorbing certain wavelengths of light and reflecting others. The colour we see is the colour of the light reflected by the object. This matches term 2. Reflection.
\nB. Colour observed through a coloured glass: Coloured glass allows certain wavelengths of light to pass through while absorbing others. The colour we see is the colour of the light transmitted through the glass. This matches term 3. Transmission.
\nC. Bending of the image of a rod partially dipped in water: This phenomenon occurs because light changes speed as it passes from one medium (air) to another (water), causing it to bend at the interface. This bending of light is called refraction. This matches term 4. Refraction.
\nD. Shining observed when one steps on an earthworm: With A, B, and C matched to 2, 3, and 4 respectively, the remaining term for D is 1. Fluorescence is the emission of light by a substance after it has absorbed light. While shining can often be explained by reflection, it is possible that some biological substances exhibit fluorescence. Given the other standard matches, this is the most likely intended pairing in the context of the question’s options.
\nMatching: A-2, B-3, C-4, D-1. This corresponds to option D.
\n<\/section>\n
\nUnderstand basic optical phenomena: Reflection (light bouncing off a surface), Transmission (light passing through a substance), Refraction (bending of light as it passes from one medium to another), and Fluorescence (emission of light after absorbing radiation). Apply these concepts to everyday observations.
\n<\/section>\n
\nWhile “shining” is most commonly associated with reflection, the options force a match with Fluorescence for the last item. It’s possible the question refers to a specific, perhaps less common, property of earthworm mucus or tissues under certain conditions, or it might be a less precise pairing designed within the options provided. However, the matches for A, B, and C are definitive.
