Explanation:
Detailed explanation-1: -Opaque objects are those that do not allow light to pass through them whereas transparent objects allow light to pass through them. Therefore, wood is an opaque object but glass is transparent in nature.
Detailed explanation-2: -Wood’s lack of transparency comes from the combination of its two main components, cellulose and lignin. The lignin absorbs light, and the presence of chromophores-light activated compounds-in the material makes the wood look brown.
Detailed explanation-3: -Wood, stone, etc., are opaque materials. Translucent materials allow partial transmission of light through them.
