Light and sound

• Pitch is high or low a sound is
• Amplitude is measured in meters
• Greater amplitude is more is energy sound is having
• Wave length is the length of the wave
• Frequency is the number of waves passing through a point per second
• Pitch of sound are determined by the frequency of the vibration of the sound waves that produce them
• Sound waves with a low frequency produce low pitch
• The amplitude of a. Sound wave determines it's loudness and volume
• A smaller amplitude means quieter sound
• Transverse is a light wave that is perpendicular
• Longitudinal is sound wave that determine the direction of the wave
• The pinna is the outside of the ear
• The ear-canal is the narrow path to the ear
• The ear drum vibrates the sound to the three bones
• The three bones are called hammer anvil and stirrup and they vibrate sending sound waves to the cochlea
• The cochlea send electrical impulses to the auditory nerve and then it sends it to the brain which translates to sounds
• If sounds are too loud they move fluid in the inner ear and that can damage the hair cells
• Damaging the ear can make the ear hairs less sensitive to sound which can lead to hearing loss
• Loud and repeated sounds can cause temporary or permanent hearing loss
