Question

Consider the following statements:
1. The albedo of an object determines its visual brightness when viewed with reflected light.
2. The albedo of Mercury is much greater than the albedo of the Earth.
Which of the statements given above is/are correct?

Accepted Answer

The first statement is correct because albedo is a measure of the reflectivity of a surface. It represents the proportion of incident light that is reflected by an object. Therefore, a higher albedo means the object appears brighter when viewed via reflected light.

The second statement is incorrect. The Earth has an average albedo of approximately 0.30, largely due to its cloud cover, ice, and snow, which are highly reflective. In contrast, Mercury has a dark, rocky surface with almost no atmosphere or clouds to reflect light, resulting in a much lower albedo of about 0.12. Thus, the albedo of Earth is significantly greater than that of Mercury.

Since only the first statement is true, the correct option is A.
