Waves

Waves

1. Electromagnetic spectrum

   • Radio/tv highest wavelengh lowest frequency
   • Microwaves
   • Ir

2. Definitions

   • Frequency (f)
     • Number of waves pass a point in 1 second
     • Hz
   • Wavelengh
     • Horizontal distance between two corresponding points on wave
     • M
   • Amplitude
     • Half the vertical distance between crest and trough
     • M
   • Period (t)
     • Time taken for one wave to pass a point

3. Formula

   • V=f*wavelength
   • f=1/t
   • d=v*t
