Electromagnetic Waves

QuestionAnswer
diffraction bending of waves by passing through an opening, around obstacles or by sharp edges
electromagnetic spectrum the entire range of electromagnetic waves as shown in both frequencies and wavelengths
electromagnetic wave transverse waves that do not require a medium through which to travel and are produced by an oscillating charge
radiation transfer of energy by electromagnetic waves
trough lowest point between two waves
wavelength distance between two crests
crest high point of a wave; peak
amplitude distance between crest or peak (highest amplitude value) and trough (lowest amplitude value)
RoyGBiv colors of rainbow (red, orange,yellow, green, blue, indigo, violet)
visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV).
x-rays between UV radiation and gamma rays
gamma rays penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei
radio waves electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared
frequency number of wave crests that pass a point in one second; the unit is Hertz (Hz)
Inversely proportional wavelength and frequency are inversely proportional
wave spectrum radio wave, microwave, infrared, visible, ultraviolet radiation, X-Ray, gamma-ray
