<p> BASIC PROPERTIES AND BEHAVIOR OF WAVES NOTES </p><p>Standard 8.P.3: The student will demonstrate an understanding of the properties and behaviors of waves. </p><p>Performance Indicator8.P.3A.2: Develop and use models to exemplify the basic properties of waves (including frequency, amplitude, wavelength, and speed). </p><p>PROPERTIES OF A TRANSVERSE WAVE</p><p>The highest point of a transverse wave is the crest and the lowest point is called a trough. </p><p>Frequency (NUMBER OF WAVES THAT PASSES THROUGH)</p><p>• ● Frequency is a measure of how many waves pass a point in a certain amount of time. The higher the frequency, the closer the waves are together and the greater the energy carried by the waves will be. </p><p> Frequency is measured in Hertz or cycles per second. The frequency is often represented by the lower case “f.”</p><p>• The formula for frequency is: f=1/T (T means Time or Period)</p><p>• Amplitude (HEIGHT OF THE WAVE)</p><p>● Amplitude is a measure of the distance between a line through the middle of a wave and a crest or trough. </p><p>● The greater the force that produces a wave, the greater the amplitude of the wave and the greater the energy carried by the wave. </p><p>● In a transverse wave the higher the wave, the higher the amplitude. </p><p>● Sounds with greater amplitude will be louder; light with greater amplitude will be brighter. </p><p>• Wavelength (DISTANCE OF A WAVE FROM CREST TO CREST OR TROUGH TO TROUGH)</p><p>1 ● Wavelength is a measure of the distance from the crest on one wave to the crest on the very next wave. 2 ● Shorter wavelengths are influenced by the frequency. </p><p>3 ● A higher frequency causes a shorter wavelength and greater energy. </p><p> The wavelength is usually represented by the Greek letter lambda </p><p>4 Speed or Velocity of a Wave </p><p>5 ● Speed is a measure of the distance a wave travels in an amount of time. </p><p>6 ● The speed of a wave is determined by the type of wave and the nature of the medium. </p><p>7 ● As a wave enters a different medium, the wave’s speed changes. Waves travel at different speeds in different media. For example: sound travels at different speed in air than in water.</p><p>8 ● All frequencies of electromagnetic waves travel at the same speed in empty space. </p><p> The velocity can be found by multiplying the frequency by the wavelength. </p><p>RECAP- MOVEMENT OF TRANSVERSE VS. LONGITUDINAL WAVES LABEL THE CREST, TROUGH, AMPLITUDE AND WAVELENGTH OF THE TRANSVERSE WAVE</p><p>LABEL RAREFACTION, COMPRESSION AND WAVELENGTH ON THE COMPRESSIONAL/LONGITUDINAL WAVE</p>
