Yes, infrared radiation can pass through wood as wood is mostly transparent to infrared radiation. Infrared radiation, in the wavelengths typically used in infrared heating, is generally around 5-15 microns.
Traveling within this range, the infrared radiation can easily penetrate wood. The actual penetration distance will depend on the size and density of the material, but for the most part, most infrared radiation can pass through a piece of wood with ease.
Additionally, the distinct wavelength of radiation from an infrared heater can easily pass through wood and still provide the same amount of heat as it would in open space.

What materials can infrared pass through?
Infrared, which is a form of electromagnetic radiation that is not visible to the human eye, can pass through many materials. Examples of materials that infrared can pass through include air, clouds, thick cloth, light glass, thin plastic, and certain other materials.
Additionally, infrared can pass through certain materials that are opaque to visible light, such as solid objects, fog, and smoke. Some materials, such as water, are opaque to infrared wavelength, so infrared radiation will not pass through it.
In terms of applications, infrared is used in many ways. It is used in thermal imaging cameras and other security systems, remote sensing, medical imaging, industrial heating, communications, and more.
What materials are transparent to IR?
Materials that are transparent to infrared (IR) light include optical glass, water, some plastics, some tempered glass, black cloth, and many common household materials like paper, cardboard and cotton fabric.
Most materials that are transparent to visible light will also be transparent to infrared. However, due to the fact that infrared light has a longer wavelength than visible light, certain materials can be opaque to visible light but still be transparent to IR.
Examples of materials like this include many types of dark-colored plastic, ceramic tiles, and some metals. Additionally, some IR-transparent materials can be used to construct filters and coatings that will only allow some, but not all, wavelengths of infrared light to pass through easily.
The ability of a material to transmit infrared light can vary greatly depending on the wavelength and the intensity of the light being used.
Does infrared bounce off walls?
Yes, infrared light can bounce off walls and other surfaces just like visible light can. Certain objects can even reflect infrared radiation more efficiently than visible light, which is why hot objects are more commonly seen in night vision cameras since they have strong infrared reflectivity.
The same surfaces that already reflect visible light, such as glossy walls, will also reflect infrared radiation, though not as strongly. Other materials, such as glass, painted surfaces, and fabrics, can also reflect infrared radiation, though their reflection usually varies with the wavelength.
As a result, infrared radiation can easily bounce off walls and other surfaces, though the amount of reflection depends on the surface characteristics and angle of incidence.
Can you XRAY through wood?
No, X-rays cannot pass through wood. X-rays have a limited ability to pass through objects and materials because they involve high energy particles that can interact with matter. They can pass through many substances like paper, cloth, and skin, but not solid objects such as wood, metal, and stone.
X-rays are able to penetrate organic materials because they are low in atomic number and therefore make it easier for them to penetrate. Hard materials, like metals and rocks, have high atomic numbers that make it harder for the X-rays to make it through.
This is why the images produced by an X-ray machine will show bones as bright (white) and tissues as dark (black).
Can Xrays pass wood?
Yes, Xrays can pass through wood, though their effectiveness is diminished. The density of wood is relatively low, so it can be penetrated by Xrays but also absorb a significant amount of the radiation.
Additionally, since wood consists of different organic molecules, it will scatter the Xrays more than substances such as metal or air. As a result, the Xrays that make it through wood are significantly weakened and blurred, making it difficult to get a clear image of what is behind the wood.
