The Electromagnetic spectrum

The Electromagnetic spectrum

1. Radiowaves

   • Microwaves
     • Infra red
       • Visible light
         • Ultra violet
           • X rays
             • Gamma rays
               • MRI scanner
             • X ray machine
           • Sunbed
         • Lightbulb
       • Remote
     • Microwave
   • Tv

2. Wavelength and frequency

   • Higher the frequency=Lower the wave length
   • Higher the frequency= lower the wavelength

3. Wavespeed= frequency x wavelength

4. Measurements

   • Frequency= Hz
   • Wvelength= m
   • Wavespeed= m/s

5. How to measure

   • One point to another= Wavelength
   • Number of waves= frequency
   • Amplitude= Area from no disturbance
