Light as a wave: Light can be described (modeled) as anelectromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. What Is Light? 28 related questions found Wh...
meaning that all sounds are absorbed by the room itself. To achieve this, anechoic rooms are lined with fiberglass wedges that cover the entire ceiling, floor and walls. This creates an uneven surface of a wedge network protruding from different directions...
Light is an electromagnetic phenomenon. A changing electric field creates a magnetic field, and vice versa, and the frequency of the changes creates the pulses that form a beam of light. Light travels at a constant speed when traveling through a vacuum, but when traveling through a medium the...

These include a piezoelectric ceramic element that creates and distributes ultrasonic sound waves. Sound waves travel to an object from a piezoelectric transducer through material called a couplant. The couplant is usually water. Sound waves bounce off the object and return to the transducer in the...
and henry is the si unit of inductance . 1 henry is defined as the amount of inductance required to produce an emf of 1 volt in a conductor when the current change in the conductor is at the rate of 1 ampere per second. an electric current flowing through a conductor creates a magnetic...
What is an electron in quantum physics? What dictates the energy of a mechanical wave? What does 'energy expressed' mean in quantum physics? What determines the color of a photon? Which energy level requires the most energy to remove an electron? What creates an electric force field that mov...
Choosing an Electromagnetic Flow Meter Magnetic flowmeters can detect the flow of clean, multi-phase, dirty, corrosive, erosive, or viscous liquids and slurries as long as their conductivity exceeds the minimum required for the particular design. The expected inaccuracy and rangeability of the better...
The combination of objects in the pairing creates a unique gravitational wave pattern. Despite this, the generation mechanism for this class of gravitational waves is the same no matter the source. Known as "inspiral" this process occurs over millions of years as the dense objects revolve ...
the explanation only accounts for telepathy, not clairvoyance or precognition. Presumably, if the information transfer occurs as electromagnetic energy, it has to be sent by someone; it has to travel from mind to mind. It doesn't explain how information would move through time or from an objec...
