Albido is a measurment of the percentage of light that is :-

Options

A. Absorbed by an object surface
B. Converted into sugar by photosynthesis
C. Reflected by surface
D. Reflected by atmosphere

Answer

**Step-by-Step Solution:**

1. **Understanding Albedo**: Albedo is a term used in ecology and environmental science to describe the reflectivity of a surface. It is a measure of how much light that hits a surface is reflected without being absorbed.

2. **Identifying the Options**: The question provides three options regarding what albedo measures:
- A) Absorbed by an object surface
- B) Converted into sugar by photosynthesis
- C) Reflected by surface or atmosphere

3. **Analyzing the Options**:
- Option A (absorbed by an object surface) refers to the light that is taken in by the surface, which is not what albedo measures.
- Option B (converted into sugar by photosynthesis) pertains to the process of photosynthesis and does not relate to the concept of albedo.
- Option C (reflected by surface or atmosphere) correctly describes albedo as it measures the percentage of light that is reflected off a surface.

4. **Conclusion**: Since albedo specifically measures the reflectivity of a surface, the correct answer is Option C: "reflected by surface."

5. **Final Answer**: The correct option is C) reflected by surface.
