Here's why:

* Albedo is a measure of how much light a surface reflects. It's a percentage, with 0% meaning no reflection (like a black hole) and 100% meaning all light is reflected (like a perfect mirror).

* High albedo means the surface reflects a large amount of light. Think of fresh snow, which appears very bright because it reflects a lot of sunlight.

* Low albedo means the surface absorbs more light and reflects less. Dark asphalt, for example, has a low albedo and absorbs a lot of sunlight, making it appear darker.

Therefore, an object with a high albedo will appear brighter than an object with a low albedo because it reflects more of the light that hits it.
