waves/p6

waves/p6

1. amplitude

   • the hight of the wave above the centre line
   • wavelength
     • the distance between two indentical points on a wave e.g two peaks
       • the units of wavelength are metres

2. frequency

   • how many waves go past in one seconded
     • units of frequency are hertz

3. pitch

   • how high and low the sounds

4. volume

   • how loud the sound is

5. microphone

   • takes sound waves and turns them into a sound wave

6. the ear

   • pinna
     • ear canal
       • ear drum
         • ossicles
           • hammer anvil stirrup
           • cochlea
             • tiny hairs move and convert the sound wave into electricalsignal
             • auditory nerve
               • brain
             • it make it vibrate and the vibratshion goes into the brain and sound is hera able

7. speaker

   • takes electrical signals and turns them into a sound waves
