Understanding Wave Properties in Matter

Learn about wave characteristics and properties such as frequency, wavelength, amplitude, crest, trough, compression, rarefaction, transverse, and longitudinal waves. Understand the difference between transverse and longitudinal waves and the concept of variables in science experiments.

  1. Properties of Matter Monday, September 30, 2014 Mrs. Hensley Sedgefield Middle School

  2. DO NOW! In your scientific journal, define the following: Wave Frequency Crest Trough Wavelength Amplitude Transverse Longitudinal Compression Rarefaction

  3. Check your work! • Wave – a disturbance on the surface of a liquid body in the form or a moving ridge or swell. • Frequency – the rate at which a wave occurs

  4. Check your work! • Crest – the highest part of a wave • Trough – the lowest part of a wave

  5. Check your work! • Wavelength – the distance between two equal points of a wave, either the crests or the troughs. • Amplitude – is the measurement of the top or bottom half of a wave.

  6. Check your work! • Transverse – the motion is at right angles to the direction of the wave. • Longitudinal – the motion is parallel to the direction of the wave.

  7. Check your work! • Compression –the part of the wave where the movement is closest together. • Rarefaction – the part of the wave where the movement is furthest apart.

  8. Compression and Rarefaction

  9. Transverse and Longitudinal • http://www.edinformatics.com/math_science/transverse_longitudinal_waves.htm

  10. Amplitude – it is 1, in this example.

  11. What is a Variable? A variable is a word for a quantity of condition that can change.

  12. Independent Variable • Is a variable that can be controlled. • For example, in an experiment in growing a plant. You can control how much light the plant will get.

  13. Dependent Variable • You have no control over this variable. You want to observe what happens when you change the independent variable.

  15. Exit Ticket In your scientific journal, draw a longitudinal wave with a compressions and rarefactions.
