Study Notes
Sound Waves
- Sound travels as longitudinal waves, where particles of the medium vibrate parallel to the wave direction.
Sources of Sound
- A vibrating body is always a source of sound energy, creating waves that propagate through a medium.
Sensitivity to Vibrations
- Our ears contain structures that are sensitive to vibrations, allowing us to perceive sound waves.
Energy Transfer
- Sound transfers energy from one location to another, allowing us to hear it even at a distance from the source.
Definition of Sound
- Sound is a form of energy that results from the vibrations of particles in a medium, such as air, water, or solids.
Eardrum Function
- The eardrum serves to convert sound waves into mechanical vibrations, essential for hearing.
Energy Form
- Sound is considered a form of mechanical energy as it involves the motion of particles to carry the wave.
Particle Movement
- To transfer sound energy, particles of the medium compress and rarefy, creating zones of high and low pressure.
Brain Interpretation
- Our brain interprets electrical impulses generated by sound waves as recognizable sounds, enabling us to understand what we hear.
