Some methods for sound amplification of GHz–THz have been proposed so far. Some have been explored only theoretically [17] [18] and others have been explored in non-coherent experiments. We note that acoustic waves of 100 GHz to 1 THz have wavelengths in nanometre range. Sound amplification according to the experiment taken in the University ...
The exploding wire method or EWM is a way to generate plasma that consists of sending a strong enough pulse of electric current through a thin wire of some electrically conductive material. The resistive heating vaporizes the wire, and an electric arc through that vapor creates an explosive shockwave .
The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much 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 sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly, emitting a burst of light.
Smallest Transformers Soundwave with Jaguar (2003) Part of the first wave of the Japan-only Smallest Transformers toy line. Despite the small size (roughly 2 inches in robot height), the toy is virtually faithful to the original G1 toy in design and transformation. Soundwave also comes with a micro cassette that transforms into Ravage. [15]
Most experiments on the Z machine run the current discharge through a conductive tube (called a liner) filled with gas. This approach is known as magnetized liner inertial fusion, or MagLIF. The compression of a MagLIF Z-pinch is limited because the current flow is highly unstable and rotates along the cylinder which causes twisting of the ...
This experiment demonstrated that the propagation of sound is mediated by the air, and that in the absence of the air medium, the sound waves cannot travel. This experiment is often used as a classroom science experiment, where the experiment is repeated with an item such as an alarm clock placed under a bell jar, and the noise of the alarm ...
The experiments describe what appeared to be two different phenomena: the motional EMF generated when a wire moves through a magnetic field (see Lorentz force), and the transformer EMF generated by a changing magnetic field (due to the Maxwell–Faraday equation).
