Explanation

### Step-by-Step Solution:

1. **Understanding Infrared Radiation**:
Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. It is commonly associated with heat.

2. **Application 1: Night Vision Devices**:
One of the primary applications of infrared radiation is in night vision technology. Night vision devices use infrared radiation to allow us to see in low-light conditions. These devices detect the infrared light emitted by objects and convert it into a visible image, enabling us to see in the dark.
