    Body Waves
In summary: Therefore, the neutrino beam will pass through the body without being distorted or refracted in any significant way. In summary, all known waves will interact with a human body, but the interaction with neutrino beams is negligible and will not cause any significant distortion or refraction.

I was just wondering, are there any waves that can pass through the human body in a straight line, without being distorted or refracted in anyway?

"Not in any significant way" yes. "not at all" no, as a human body is made out of matter and all (known) waves interact with matter.

What kind of wavelength would be needed for this and would polarising the wave (to ensure only 1 beam went through) make it too weak to get through?

That depends on the type of wave. In general, all types of waves don't care much about objects significantly smaller than their wavelength, so you are looking for long wavelengths.

For electromagnetic waves, either long waves or very short ones (gamma rays - then you will get some absorption, but nearly no refraction) will work.

Gravitational waves of any wavelength won't care about a human body as its mass is negligible (insert your mom joke here).

Our human body is about four-fifths water. Yes, waves may indeed pass through the body. An obese person may be considered mechanically similar to or equivalent to a big oval bag full of water with extremities. If a large but short compressive force is applied to one area we may expect a hydraulic shock wave that emanates from the application point and travel throughout the entire volume. The energy contained in the pressure wave will perturb and even deform any extremity. We can study fluid dynamics easily in nature. The idea is, be ready to recognize opportunities for research whenever and wherever they appear.

What about the neutrino beam density waves

There is no neutrino beam with something I would call "density wave". Most neutrino beams are pulsed, but that is not wave-like.
The interaction probability of a neutrino in a human body is negligible.
 

1. What are "waves that can pass through the body"?

"Waves that can pass through the body" refer to types of energy that can travel through the human body without causing harm or damage. These waves include sound waves, radio waves, and certain types of electromagnetic waves.

2. How do these waves pass through the body?

These waves are able to pass through the body because they have a long wavelength and low frequency. This allows them to easily travel through the spaces between cells without interacting with the body's tissues or organs.

3. What are the applications of these waves in medicine?

These waves have many medical applications, such as ultrasound imaging, MRI scans, and radiation therapy. They can also be used to heat and destroy cancer cells without harming surrounding healthy cells.

4. Are there any potential risks associated with these waves?

In general, these waves are considered safe and non-invasive. However, overexposure to certain types of waves, such as X-rays, can be harmful to the body. It is important to follow safety guidelines and limit exposure to these waves.

5. How do scientists study these waves in the body?

Scientists use a variety of imaging techniques and instruments, such as ultrasound machines and MRI scanners, to study how these waves interact with the body. They also conduct experiments to measure the effects of these waves on different tissues and organs.
