The radiation that bounces back from Earth after absorbing the Sun's energy is called reflected solar radiation. It's also sometimes referred to as albedo.

Here's a breakdown:

* Solar radiation: The energy emitted by the Sun, consisting of light and heat.

* Earth's atmosphere and surface: Absorb some of this incoming solar radiation.

* Reflected solar radiation: The portion of the solar radiation that bounces back into space without being absorbed.

This reflected radiation contributes to Earth's energy balance and plays a role in regulating the planet's temperature.
