Transcript of "Types of waves with compressional waves"

  1. 1. Types of Waves<br />
  2. 2. Waves<br />A wave is a back and forth motion that carries energy through matter or through space.<br />
  3. 3. Characteristics of a Wave<br />The highest points on a wave are called crests.<br />The lowest points are called troughs.<br />
  4. 4. Characteristics of a Wave<br />Wavelength is the distance between one crest or trough to the next. <br />
  5. 5. Characteristics of a Wave<br />Amplitude is a measure of the wave’s height from the resting position.<br />Amplitude is equal to one-half of the vertical distance between a crest and trough.<br />Waves with larger amplitudes carry more energy.<br />
  6. 6. Characteristics of a Wave<br />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.<br />The higher the frequency, the more energy the wave carries.<br />Frequency is measured in units of hertz (Hz).<br />One Hz = one wave per second.<br />
  7. 7. Two types of waves<br />Waves are generally one of two basic types:<br />Mechanical <br />Electromagnetic<br />
  8. 8. Mechanical Wave<br />Mechanical waves travel through matter by creating vibrations in a medium.<br />The medium can be any type of matter:<br />Solids<br />Liquids<br />Gases<br />Examples of Mechanical waves:<br />Sound<br />Seismic waves<br />Water waves<br />
  9. 9. Electromagnetic Waves<br />Electromagnetic waves are not caused by a disturbance of particles in a medium.<br />It is produced by an interaction between an electric and magnetic field.<br />Examples:<br />X-rays<br />Microwaves<br />Radio waves<br />Visible light<br />
  10. 10. Electromagnetic Spectrum<br />An electromagnetic spectrum is a range of radiant energy arranged in order of wavelength and frequency. <br />
  11. 11.
  12. 12. Radio Waves<br />Have some of the longest radio wavelengths of all electromagnetic waves. <br />Low energy waves.<br />Radio and Television stations use radio waves.<br />
  13. 13. Microwaves<br />Short wavelengths<br />High frequency<br />Carry more energy than radio waves<br />Uses:<br />Cell Phones<br />Radars<br />Microwave ovens<br />
  14. 14. X-Rays and Gamma Rays<br />X-Rays<br />High energy<br />Short wavelengths<br />Greater penetrating power<br />Gamma Rays<br />More energy than X-Rays<br />Produced by some nuclear reactions<br />
  15. 15. Other types of waves<br />Infrared waves<br />Carry more energy than microwaves<br />Visible light<br />Can be seen with human eye<br />Contains all colors of light<br />Ultraviolet light<br />Short wavelength<br />Greater energy than visible light<br />
  16. 16. Compressional Waves<br /> A wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.<br />
