waves

waves

1. wavelenght or lambda

   • lambda= v/f
   • distance between one point on one wave to the next

2. wave speed or v

   • v=f times lambda

3. ferquency or f

   • f=lambda/v
     • number of waves porduced each second

4. vibrations that transfer energy

   • without matter being transferred

5. mechanial must travel through a meidan

   • soilds,liquids and gases
   • sound wave
   • seismic waves
   • can't travel through a vaccum
     • space

6. electro magnetic need to travel through a meidan

   • can travel through a vaccum
   • light
   • mricowaves
   • infrared light

7. transverse waves

   • vibrations
     • right angle
       • energy transferred
       • direction traveled

8. longitudinal

   • vibrations
     • same direction
       • energy transferred
       • direction traveled

9. amplitdude

   • the height of the wave

10. diffraction

    • wave meets gap in a barrier
      • the wave spreapds out
