MCQ
उत्तर
Glass
Explanation:
A diathermanous substance is a material that allows thermal radiation (heat) to pass through it without significant absorption.
- Glass is diathermanous because it allows heat radiation to pass through, especially in the visible and infrared spectrum.
- Wood, iron, and copper are adiathermanous (they do not allow heat radiation to pass through easily; instead, they absorb or reflect it).
