Sonoluminescence: Creating Light From Sound

Image
Nature is full of wonders, sometimes what you see is unbelievable and the other time, what you believe may not be part of nature.  Sonoluminescence is one such counter intuitive phenomenon, which is very rare and took scientists off guard. What more, this phenomenon is demonstrated by a tiny critter in the ocean, Mantis Shrimp. What is Sonoluminescence? Sono means sound, while lumen means light. The word literally means creation of light from sound, which may sound impossible , as it was to me in the beginning but there is scientific explanation to it.  Technically, it is a pulse of light, which is generated when a bubble collapse over itself. This bubble is generated by the sudden outburst of sound. It is basically a conversion of acoustical or sound energy into light energy which is part of nucleation, growth and collapse of bubbles in liquid. 2) Behind the scene There is more to it, the bubble generated during this process makes the surrounding water h...

Prince Rupert's Drop: Resist Hammer Blow, Yet Shatter With A Twitch

Image
Have you ever heard of an object which is as fragile as glass but as indestructible as a tank? Last week I came across one such wonder of science which can be broken with an ease of twitch but can take the blow of the hammer. Of course, it all depends on placement of force. Prince Rupert's Glass drop has an impossible property. Researches were carried out in the 20th and 21st centuries to understand the reasons that why the drop has contradictory properties. But the history of the drop can be traced back to 1660 that is more than 350 years from now when Prince Rupert of the Rhine, brought them to England, thus got the name.  They were studied by the Royal Society, and the principles behind the unusual properties might have probably led to the development of the process to produce toughened glass, which was patented in 1874. although they were reportedly being produced in the Netherlands earlier in the 17th century and had probably been known to glass makers for much longe...
