wave and motion
Question | Answer |
---|---|
Wave | A wave is any disturbance that transfers energy through matter or space. |
Medium | the matter through which a wave can travel (can be solid, liquid, or gas) |
Frequency | the number of waves that pass by a point each second |
Amplitude | larger amplitude = more energy,wave height |
Wavelength | distance between 2 crests or troughs |
Wave Speed | speed at which waves travel through a medium |
Longitudinal Wave | waves in which the particles vibrate back and forth in compressional pulses. |
Mechanical Wave | can be either Transverse or Longitudinal and also needs a medium to travel tthrough |
Transverse Wave | waves in which the particles vibrate in an up and down motion. |
Electromagnetic Wave | Waves are ALWAYS transverse waves. |
crest | highest point, or peak, of a transverse wave |
rarefaction | where particles are spread apart in a longitudinal wave |
compression | where particles are bunched together in a longitudinal wave |
