WebLove waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. Of the two surface waves, Love waves move faster. Rayleigh waves cause the ground to shake in an elliptical pattern. This motion is similar to that observed in ocean waves. WebUV waves have a defined electromagnetic spectrum between 10 nm to 400 nm. UV waves of different ranges of wavelengths have different characteristics based on their structure. Phenomenons such as the sterilisation effect, effect on DNA, Rayleigh scattering, and oxidation upon ozone help us better understand the ultraviolet waves.
