Waves test review.

Frequency

The amount of waves that pass a certain point in one second. (Measured in HZ)

Wave

Waves are a disturbance that moves energy from one place to another.

Medium

Solid,Liquid or Gas

Wavelength

The distance between one point in a wave to the next point in a wave.

Crest

The highest point in a wave.

Trough

The lowest point in a wave.

2 major types of waves.

Mechanical and Electromagnetic.

Amplitude

How much energy a wave has.

Amplitude of a sound wave.

The amount of sound a sound wave has.

Frequency of a sound wave.

How much sound passes a certain point in one second.

Electromagnetic waves

A wave that can travel without a medium.

Examples of electromagnetic waves.

Light waves, Radio waves, X-rays, Ultraviolet light, microwaves.

Mechanical wave.

A wave that does need a medium to travel.

Examples of mechanical waves.

Ocean waves, waves on a string, seismic waves.

Compression

An area on the wave where the medium becomes more dense.

Rarefaction

An area on a wave where the medium is less dense.

Wavelength of a compressional wave

Distance from one point of a wave to the nearest point like it. Such as compression to compression or rarefaction to rarefaction.

Amplitude

The amplitude depends on the density of the medium in compressional and rarefactions. The greater amplitude the more energy the wave carries.

Reflection

The process by which wave hits and object and bounces off of it.

Absorption

When a wave hits a material and its not reflected back instead it gets sucked in.

Transmission
