P6 - Waves

1. Heatz

   • The Unit of Frequency
   • Pitch
     • A 'high' or 'low' sound is

2. Microphone

   • Converts sound waves into an electrical signal

3. Frequency

   • The Number of vibrations per second

4. WaveLength

   • The distance between two peaks or troughs

5. Loud Speaker

   • Converts a Electrical signal into sound waves

6. Waves

   • Lonitudinal
     • Vibrations
       • Compressions
         • Medium
           • A substance through which waves travel
         • The Part of a wave where particles are closer together
       • A 'to and fo' repeated movement
     • Vibrations in the same direction as the wave movement
       • Rarefaction - Where the particles are far apart
   • How Sound energy is transmitted

7. Types Of Waves

   • Transverse
     • The waves move across e direction of travel
       • Like light waves or water waves

8. The speed of sound

   • Sound travels fastest in solids
   • In Water sound travels at a slow paste (1500m/s)
     • In air sound travels at (330 m/s)
   • Sound Does not travel in a vacuum

9. The Ear

   • Pinna
     • Ear Canal
       • Ear Drum
         • Ossicles
           • Hammer,Anvil,Stirrup
           • Cochlea
             • Auditory Name
               • Brain
             • Tiny Hairs Move and convert the sound wave into an eletrical singal
