A novel way to find aliens might be through gravitational wave detection, Loeb says. He is interested in laser interferometry ...

All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back ...

Electromagnetic waves can be separated into seven distinct groups in the spectrum. Each group contains a range of frequencies. For example, visible light contains all the frequencies that can be ...

yet they are all forms of electromagnetic radiation—waves moving through space (not just outer space) that have an electric and magnetic component and are delivered by massless particles called ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

The Japan-based company is offering two products: THz photomultiplier tube (THz PMT) modules, and THz image intensifiers (THz I.I.), which can detect THz wave pulse signals at high speed and with high ...

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. The greater the amplitude of a wave then the more energy it is ...
