Answer 1

Among the options provided, microwaves have the greatest wavelength.

Here’s a brief comparison:
- **Microwaves**: Longer wavelengths, typically ranging from about 1 millimeter to 1 meter.
- **Infrared light**: Wavelengths range from about 700 nanometers to 1 millimeter (shorter than microwaves).
- **Visible light**: Wavelengths range from approximately 400 to 700 nanometers (shorter than infrared).
- **X-rays**: Have much shorter wavelengths, ranging from about 0.01 to 10 nanometers.

So, the correct answer is **microwaves**.
