Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Low emissivity coatings reduce heat loss from greenhouse glass and improve energy conservation.
Step 1: In a greenhouse, solar radiation enters through glass and warms the inside.
Step 2: At night or in cold weather, heat may be lost through the glass surface.
Step 3: Low emissivity coating reduces thermal radiation loss from the greenhouse.
Step 4: Metal oxide coatings are widely used because they allow useful light transmission while reducing heat loss.
Step 5: Therefore, the most widely used low emissivity coating is metal oxide. \[ \boxed{\text{Metal oxide}} \]
