   • they are waves that need to pass through some matter

3. transverse waves

4. longitudinal waves

   • what is?

5. how to measure

   • amplitude
     • the intensity of the wave
   • wave lenth
     • is the distance between 2 corresponding points of the wave
   • distance
     • the distance that the wave have advanced

6. speed of a wave

   • is how fast the wave is moving
   • is represented in v

7. frequensy

   • is the number of times per sec that the wave cycle
   • is measured in hertz
     • is represented by the lower case f

8. period

   • the period is represented T
