WebInfrared light is one of the lights we can see with special cameras. Infrared light shows us how hot things are. It can also show us how cold things are. But it all has to do with heat. Our bodies give off heat in waves. Animals like dogs and cats give off heat too. With special infrared cameras, you can see the heat. WebLight sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that comes from them. Incandescence [ edit]
WebNov 6, 2016 · To emit light you have to be a source of light and the Moon is not a source of light. The Moon REFLECTS light. The light it reflects comes from the Sun (which does … The bubble will then begin to emit light. The light emission of highly compressed noble gas is exploited technologically in the argon flash devices. During bubble collapse, the inertia of the surrounding water causes high pressure and high temperature, reaching around 10,000 kelvins in the interior of the … See more Sonoluminescence is the emission of light from imploding bubbles in a liquid when excited by sound. Sonoluminescence was first discovered in 1934 at the University of Cologne. It occurs when a … See more Main article: Rayleigh–Plesset equation The dynamics of the motion of the bubble is characterized to a first approximation by the Rayleigh–Plesset equation (named after Lord Rayleigh and Milton Plesset): This is an … See more Pistol shrimp (also called snapping shrimp) produce a type of cavitation luminescence from a collapsing bubble caused by quickly snapping its claw. The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures … See more The sonoluminescence effect was first discovered at the University of Cologne in 1934 as a result of work on sonar. Hermann Frenzel … See more Sonoluminescence can occur when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly. This cavity may take the form of a pre-existing bubble, or may be generated through a process known as cavitation.
