Study Notes
Waves and Mediums
- A wave is a disturbance that carries energy through matter.
- A medium is the substance through which waves travel, examples include air, water, rope, and train-tracks.
Types of Waves
- Electromagnetic waves, such as X-rays, microwaves, and radio waves, do not require a medium to travel and are transverse waves.
- Mechanical waves, like sound waves, require a medium and cannot travel through a vacuum.
Wave Characteristics
- All waves have three primary characteristics: amplitude, wavelength, and frequency.
- Amplitude measures the energy carried by a wave, defined as the distance from the mid-point to the crest or trough.
- Wavelength is the distance between corresponding points on adjacent waves.
Frequency and Measurement
- Frequency refers to the number of crests that pass a point per second, measured in hertz (Hz).
- Sound waves are longitudinal mechanical waves, while light travels faster than sound.
Wave Behavior
- Sound travels slower in colder temperatures, and its speed is greatest in solids due to increased density.
- Reflection occurs when waves bounce back, exemplified by echoes and mirrors.
- Refraction is the bending of waves resulting from a change in the medium's speed.
Sound Characteristics
- High amplitude waves produce loud sounds.
- Sound waves travel fastest through solids, then liquids, and slowest in gases.
Other Concepts
- Longitudinal waves are also known as compression waves.
- Sound is heard after lightning strikes because sound waves travel slower than light waves.
