Study Notes

Transverse Waves

Vibrations are perpendicular to the direction of energy transfer.
Example: Water waves

Longitudinal Waves

Vibrations are parallel to the direction of energy transfer.
Example: Sound waves

Wave Properties

Wavelength: The distance between two consecutive points in a wave (e.g., crest to crest or trough to trough). Measured in meters (m).
Frequency: The number of waves passing a point in one second. Measured in Hertz (Hz).
Amplitude: The maximum distance of a point on a wave from its rest position.
Period: The time it takes for one complete wave cycle to pass a given point.

Wave Equation

Velocity of a wave = frequency × wavelength
Units: Velocity (m/s), frequency (Hz), wavelength (m)

Measuring Waves

Ripple tank: Used to investigate waves. Steps include: measure frequency, measure distance of 10 wavelengths, divide distance by 10 to get wavelength, use wave equation to calculate speed..

Sound Speed in Different Media

Sound travels fastest in solids because particles are closest together.
Sound travels slower in liquids than solids, and slowest in gases.
Sound waves travel through solids by particles vibrating and colliding with their neighbors. This transfer of vibrations causes the sound to travel through the material.
Sound waves travel through gases more slowly, causing a delay between when a particle vibrates and the particle next to it vibrates.
Sound travels fastest in solids, slower in liquids, and slowest in gases.
In solids, sound travels faster as particles are closer together. In liquids and gases sound travels slower as the particles are further apart.
Sound travels through a medium by particles vibrating and colliding with neighbors.
