Step 1: Understand what a black body is. A black body is an idealized physical object that perfectly absorbs all light that hits it.
Step 2: Know that a black body does not reflect any light. This means it takes in all the light energy without bouncing any back.
Step 3: Recognize that this absorption happens for all types of light, no matter the color or angle it comes from.
Step 4: Remember that because it absorbs all light, a black body also emits light when it gets hot, and the color of the emitted light depends on its temperature.
