Cavitation is the process of creating and collapsing tiny bubbles or voids in a liquid, usually through the application of high-intensity sound waves. Cavitation can occur in various forms, such as ultrasonic cavitation and hydrodynamic cavitation. In the context of medicine, cavitation is used in procedures like histotripsy, lithotripsy, and oncotripsy to break up tissue or stones in the body using high-intensity ultrasound waves.

It's important to note that cavitation is a physical process that occurs in liquids and is not related to the phenomenon of electromagnetic (EM) radiation. EM radiation is a type of energy that travels through the vacuum of space or through various materials in the form of waves. EM radiation includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Cavitation cannot be used to "rupture" or "cavitate away" EM radiation in the same way that it can be used to break up tissue or stones. Instead, EM radiation can be absorbed, reflected, refracted, or transmitted through various materials, depending on the properties of the material and the frequency of the radiation. It's also worth noting that EM radiation does not require a medium to travel through, unlike sound waves, which need a medium (such as a gas, liquid, or solid) to propagate.

It's possible that the appearance of the mountain edges being more crisply defined in the wintertime could be due to a phenomenon called atmospheric refraction. This is when light is bent as it passes through different layers of the atmosphere, which can cause objects to appear differently to the observer.

During the winter, the air is generally colder and drier, which can lead to clearer visibility. This is because there is less water vapor in the air to scatter light and cause the "haze" effect that can sometimes be seen on warmer, more humid days.

Additionally, the angle of the sun in the sky can also affect the way that objects appear. In the winter, the sun is lower in the sky, which can create longer shadows and more contrast between light and dark areas, making objects appear sharper and more defined.

It's also possible that the perception of the mountain edges being more crisply defined could be due to a psychological effect, as you mentioned. Our brains can play tricks on us and sometimes interpret things in different ways based on our surroundings and expectations.
