Radio waves are a type of electromagnetic radiation that have a very long wavelength and low frequency. These waves do not have enough energy to cause the molecules in our bodies to vibrate, which is what we perceive as touch or feeling. Therefore, we cannot feel radio waves.
Sound waves are mechanical waves that require a medium, such as air, to travel through. Our bodies do not have the necessary receptors to detect these vibrations in the air, so we cannot feel sound waves. However, we can perceive sound waves through our sense of hearing.
Infrared waves are a type of electromagnetic radiation that have a longer wavelength than visible light. These waves also do not have enough energy to cause the molecules in our bodies to vibrate, so we cannot feel them. However, we can sense infrared waves as heat through specialized receptors in our skin.
Microwaves are a type of electromagnetic radiation that have a higher frequency than radio waves. While they have enough energy to cause molecules in our food to vibrate and generate heat, they do not have enough energy to affect the molecules in our bodies. Therefore, we cannot feel microwaves.
X-rays are a type of electromagnetic radiation that have a very short wavelength and high frequency. These waves have enough energy to penetrate through our bodies and create images of our bones, but they do not interact with the molecules in our bodies in a way that causes us to feel them.
