A poor emitter has a large reflectivity. Explain why.

Explanation

To explain why a poor emitter has a large reflectivity, we can break down the concepts of absorption, emission, and reflection in the context of thermal radiation. Here’s a step-by-step solution:

### Step 1: Understanding Radiation Interaction
When radiation (like heat or light) strikes a body, it can be reflected, absorbed, or transmitted. The total incident radiation can be expressed as:
\[ Q_I = Q_R + Q_A + Q_T \]
where:
- \( Q_I \) = incident radiation
- \( Q_R \) = reflected radiation
