Waves

Waves

1. wavelength is the distance from a point on one wave to the equivalent.

2. wavelength is measured in metres

3. The amplitude of a wave is the maximum displacement of a point on a wave away from its undistributed position

4. Frequency (f) is the number of complete wave passing a point in 1 second. Measured in Hertz (Hz)

   • 5Hz= 5 wavs passing throw in 1 sec.

5. wave speed= frequency x wavelength

6. In a longitudinal wave the vibrations of the particles are parallel to the direction of energy transfer

7. Longitudinal waves show areas of compression and rarefaction

   • Compression= when waves bunch up
   • Reflection when they spread out

8. Sound waves. Sound is produced by vibrating particles

   • The vibrations ale along the direction of the energy transfer
