Waves
• A wave is a back and forth motion that carries energy through matter or through space.

Characteristics of a Wave
• The highest points on a wave are called crests.• The lowest points are called troughs.

Characteristics of a Wave
• Wavelength is the distance between one crest or trough to the next.

Characteristics of a Wave
• Amplitude is a measure of the wave’s height from the resting position.
• Amplitude is equal to one-half of the vertical distance between a crest and trough.
• Waves with larger amplitudes carry more energy.

Characteristics of a Wave
• Frequency of a wave is a count of either the number of crests or the number of troughs that pass a point in a given amount of time.
• The higher the frequency, the more energy the wave carries.
• Frequency is measured in units of hertz (Hz).• One Hz = one wave per second.

Two types of waves
• Waves are generally one of two basic types:– Mechanical – Electromagnetic
![Page 8: Types of waves with compressional waves](https://reader036.vdocuments.us/reader036/viewer/2022081413/54777ffeb4af9f55358b458b/html5/thumbnails/8.jpg)
Mechanical Wave
• Mechanical waves travel through matter by creating vibrations in a medium.
• The medium can be any type of matter:– Solids– Liquids– Gases
• Examples of Mechanical waves:– Sound– Seismic waves– Water waves

Electromagnetic Waves
• Electromagnetic waves are not caused by a disturbance of particles in a medium.
• It is produced by an interaction between an electric and magnetic field.
• Examples:– X-rays– Microwaves– Radio waves– Visible light

Electromagnetic Spectrum
• An electromagnetic spectrum is a range of radiant energy arranged in order of wavelength and frequency.

Radio Waves
• Have some of the longest radio wavelengths of all electromagnetic waves. – Low energy waves.– Radio and Television stations use radio waves.

Microwaves
• Short wavelengths• High frequency• Carry more energy than radio waves• Uses:– Cell Phones– Radars– Microwave ovens

X-Rays and Gamma Rays
• X-Rays– High energy– Short wavelengths– Greater penetrating power
• Gamma Rays– More energy than X-Rays– Produced by some nuclear reactions

Other types of waves
• Infrared waves– Carry more energy than microwaves
• Visible light– Can be seen with human eye– Contains all colors of light
• Ultraviolet light– Short wavelength– Greater energy than visible light

Compressional Waves
A wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
