Waves and the Electromagnetic Spectrum
Ch. 17
2
What is an electromagnetic wave?
A transverse wave A wave that consists of vibrating electric and magnetic fields that move through space at the speed of light.
3
How are they produced? By charged particles being pushed or pulled toward or away from other charged ( + or - ) particles creating the magnetic field.
4
The Electromagnetic Spectrum
Is a complete range of electromagnetic waves placed in order of increasing frequencies. Electromagnetic waves have different wavelengths and different frequencies.
6
Electromagnetic Spectrum
Made up of the following waves and rays Radio waves Microwaves Infrared rays Visible light Ultraviolet light rays X-rays Gamma rays
7
Long wavelength and low frequency, left side, slow
Short wavelength and high frequency, right side, fast Frequency – the number of complete waves that pass through a given point in a certain amount of time. Wavelength – how long or short one wave is.
