Theirs is still so many questions accounts for unsolved mysteries in particle physics but some of them can be observed on a bench-top lab setup, and Sonoluminescence is one of those unsolved mysteries. Sonoluminescence is the emission of the short bursts of light from an implosion of bubbles in a liquid when flushed by sound. The bubbles will form if you take some water and hit it with sound waves. Those bubbles are low-pressure ambit all surrounded with the high pressure and if the outer pressure pushes in on the lower-pressure air then the bubbles will quickly collapse and when those bubbles collapse, the light comes out in flashes that lasted trillionths of a second.
But the main problem is, it’s far away from becoming clear that what the source of the light is? According to the theories- range from the tiny nuclear fusion reactions to the some type of electrical discharge,
or even condensation heating of the gases inside the bubbles and high temperatures inside these bubbles on the order of tens of thousands of degrees Fahrenheit, and taken numerous pictures of the light they produce and its measured by Physicists. But, how sound waves create these lights in a bubble, there isn’t any satisfied explanation of it.
If we talk about Sonoluminescence properties then Sonoluminescence can happen when a sound wave of adequate intensity induces a gaseous cavity within a liquid to collapse right away. This cavity may take a shape of the pre-existing bubble, or it may be generated by a process known as cavitations.
Well if it’s true that sound wave makes a light then it’s also true that right now Physicists aren’t able to explain it with fully and satisfied explanation, but, I hope they will be able to in the future….
It’s really interesting and makes you curious along with making you wanting to see it by yourselves…..
