1. 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.
