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.
