Waves are a common occurrence at the beach. Ocean waves crash onto the shore relentlessly and the water is always moving. Many people believe that the water is being moved by the wave, but in actuality, ocean waves are the transportation of energy made visible. The water is not being pushe...

The electromagnetic, or EM, spectrum is a range of electromagnetic radiation that goes from the lowest wavelength on the spectrum to the highest. The lowest frequency EM is radio waves, with their long wavelengths, and the highest frequency EM is gamma rays, which are very high energy w...
14.1 Wave Properties Energy can be transferred by particles or by waves. Types of Waves - Mechanical, Electromagnetic, & Matter Mechanical waves require medium to travel, such as air, water, & springs or ropes. EM waves do not require medium. Ex: light waves, radio waves & x-rays. They...
The direct energy cascade is provided by adiabatically evolving pulses, whose widths and carrier wavelengths decrease. The inverse cascade is due to the excitation of radiation. The spectrum is steeper than the Kolmogorov-Zakharov spectrum of wave turbulence....
The authors report results of experimental and theoretical studies of the soliton nature of laser‐induced nonequilibrium wave processes of energy transfer in solid bodies 1 μsec–10 sec after exposure to pulsed laser radiation. These results can serve as a key to the understanding of a new phe...
