WAVES

WAVES

1. WAVE LENGTH

   • Wave length is distance from 1 peak to the next
   • measured in

2. FREQUENCY

   • Frequency is how many COMPLETE WAVES there are per second (passing a certain point)
   • measured in Hertz

3. AMPLITUDE

   • height of the wave (from mid line to the peak)

4. SPEED

   • How fast it goes
   • WAVE SPEED = FREQUENCY X WAVELENGTH
     • SPEED (M/S) = FREQUENCY (Hz) x WAVELENGTH (m)
   • Also known as VELOCITY

5. Transverse Waves

   • Most are transverse
   • light
   • Ripples on water
   • waves on strings
   • slinky spring
   • Vibrations are @ 90 degrees to the DIRECTION OT TRAVEL of the wave

6. LONGITUDINAL WAVES

   • Sound/ultrasound
   • Shock Waves (seismic waves
   • Slinky spring when you push the end
   • Vibrations are along the SAME DIRECTION as the wave travelling

7. ALL WAVES CARRY ENERGY WITHOUT TRANSFERRING MATTER
