It's tricky to say what objects are "near the size of an infrared wave" because infrared radiation isn't a physical object with a size like a ball or a rock. It's a type of electromagnetic radiation, and its size is defined by its wavelength.

Here's a better way to understand this:

* Infrared radiation has a wide range of wavelengths: From about 700 nanometers (nm) to 1 millimeter (mm).

* Nanometers are incredibly small: A nanometer is a billionth of a meter.

So, objects that are "near the size of an infrared wave" would be things with dimensions in the range of nanometers to millimeters.

Examples:

* Viruses: Some viruses are around 100 nm in size, which is in the shorter wavelength range of infrared radiation.

* Bacteria: Bacteria are typically a few micrometers (µm) in size, which is also within the range of infrared wavelengths.

* Human hair: A human hair is roughly 50-100 µm in diameter.

* Red blood cells: Red blood cells are about 7-8 µm in diameter.

* Dust particles: Dust particles can vary greatly in size, but many fall within the range of infrared wavelengths.

Important Note:

It's crucial to remember that the size of an infrared wave doesn't necessarily mean an object is "visible" in infrared light. The ability to detect an object using infrared radiation depends on factors like the object's temperature, emissivity, and the sensitivity of the infrared sensor.
