HVJ Waves

Talbert HVJ Waves

Electromagnetic Spectrum Range of electromagnetic waves; includes radio waves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays
Radio Waves Have the lngest wavelength and shirtest frquesncy; used for radio, television, and radar
Infrared Rays You cannot see these waves, but you can feel them as heat
Ultraviolet Rays These waves are present in the sunlight; They can cause sunburn; are used to kill bacteria
X-rays These waves have a very short wavelength and a very high frequency; They can pass through most solid objects; They are used in medicine to form images of banes and internal organs
Gamma Rays These have a shorter wavelength and a higher frequency than X-rays; They are given off during nuclear reactions
Medium Substance through which waves can travel
Waves Disturbances that transfer energy from place to place
Compression Part of a medium where the particles are close together
Crest high point of a wave
Longitudinal Wave Wave in which the particles of the medium move back and forth in the direction of the wave motion
Rarefaction Part of a medium where the particles are far apart
Transverse Wave wave in which the particles of the medium move up and down at right angles to the direction of the wave motion
Trough Low point of a wave
Amplitude height of a wave
Frequency Number of complete waves passing a point in a given time
Hertz Unit used to meaure the frequency of a wave
Doppler Effect Apparent change in frequency of waves
