created by a vibrating electron. It's a transverse wave because the magnetic and electric fields vibrate perpendicular to each other. This wave doesn't require a medium. (EX. radio, microwave, infrared, UV, Gamma, mobile, radar, visible, x-ray.)
AM/FM= amplitude modulation/ frequency modulation
only part humans can see.
UVA, UVB, UVC. Blocked by ozone.
pass through materials like bone or metal.
require a medium. Most waves are mechanical
waves carry energy because...
they can do work
the --- the wave is, the more --- it carries.
has compressions and rarefactions, type of transverse wave. longitudinal waves can be sound waves, primary waves, or surface waves.
the particles in a surface wave move both perpendicular and parallel in the direction which the wave travels. (rayleigh waves and love waves)
has a crest and trough
amplitude and wavelengths are measurements of
---. period and frequency are measurements based on ---.
maximum distance that the particles of a wave vibrate on their rest position
the distance from any point on a wave to an identical point on the next wave.
SI unit for period
how rapidly vibrations occur in the medium
SI unit for frequency
medium which a wave will travel fastest in (solids, liquids, or gases)
an observed change in the frequency of a wave when the source or observer is moving
Primary (P) and secondary(S) waves.
