2. Pitch/frequency

   • Examples:
   • The pitch or frequency is how high or low a sound is.

3. Sound Waves

   • Transverse Wave
     • Transverse waves is when te energy is perpendicular to the direction of tavel of the sound wave. Example →
   • Longitudal Wave
     • A longitudinal wave is a sound wave that the energy moves parellel to the wave's direction of travel.
   • Sound waves are compressions

4. Ear

   • The outer part of ear(the pinna) collects the sound. The sound wave then travels through the auditory canal which concentrates the sound to the ear drum causing it to vibrate. The ear drum then amplifies the sound by vibration of bones (hammer). It is in the middle ear where sound energy is converted into mechanical energy. The cochlea in the inner ear converts the vibrations into electrical signals before sending signals to the brain. The brain then interprets the pulses as sound.
