Definition of sonoluminescence in English:
sonoluminescence
noun ˌsəʊnə(ʊ)luːmɪˈnɛs(ə)nsˌsänōˌlo͞oməˈnesəns
mass nounPhysics Luminescence excited in a substance by the passage of sound waves through it.
Example sentencesExamples
- I guess the other reason is that science finds the unexplained to be a challenge - and there's still plenty of mystery surrounding the exact chemistry or physics that cause that bright pin-point of light that sonoluminescence produces.
- For 70 years, physicists have puzzled over sonoluminescence, a process where sound waves create thousands of hot, luminous bubbles in water.
- A bubble's collapse can be extremely violent, as revealed in light emission, called sonoluminescence.
- During typical sonoluminescence experiments, spectral emission temperatures range up to tens of thousands of kelvins, and the rapidly imploding bubble walls can generate internal shock waves under certain conditions.
- But the work of this small start-up is still limited to computer modeling and trying to detect fusion neutrons from sonoluminescence.
Derivatives
adjective
Physics The final signature of bubble fusion is the coincidence between the sonoluminescent light flashes from collapsing bubbles and the neutron emission.
Example sentencesExamples
- In a controversial report last March, researchers offered evidence that such a so-called sonoluminescent bubble's implosion attains temperatures and pressures high enough to make atomic nuclei fuse together.
- Using this theory, temperatures inside the sonoluminescent bubble can be expected to reach 10 Kelvin.
- My fascination with sonoluminescent bubbles continues, in a way, in my high-speed photographic studies of drops and splashes.
- A similar data detection and analysis as described above would generate an image of the medium in terms of its sonoluminescent characteristics.
