Study Notes
Electric Circuits
- Overloading the circuit can cause the wires to overheat and even start a fire.
- The total current in a circuit increases when more appliances are connected to one outlet.
Sound and Waves
- Sound waves are classified as longitudinal waves.
- The speed of sound is affected by the molecular structure of the material it passes through.
- The speed of sound can be affected by temperature.
- Sound waves can travel through solids, liquids, and gases.
Characteristics of Waves
- Longitudinal waves have different characteristics than transverse waves.
- Frequency and wavelength can be used to compute wave speed.
Factors Affecting Sound
- The density of a medium can affect the speed of sound.
- Sound travels faster in denser mediums.
- Temperature can affect the speed of sound.
Properties of Sound
- Sound is a form of kinetic energy that travels through vibrations in the air.
- Sound is transmitted through the vibration of air particles.
- The amplitude of a wave affects the loudness of the sound.
