Mechanical Waves

Mechanical Waves

1. LONGITUDNAL

   • TRANSVERSE
     • Move perpendicular to the particles of the source of energy
   • Move along the particles

2. Representation of the vibration of particles

3. Frequency is the number of waves per unit time

   • Frequency and wave length are inversely propotional

4. Amplitude is the loudness of the wave measured using the height

5. Wavelength (lamda) can be measured by

   • Distance between crests Distance between trough Distance between two bases

6. Jamming

   • Intention
     • Same frequency to intercept
   • Interference
     • Same frequency crossing over each other

7. Refraction of waves

   • Wave front THE SOURCE OF A NEW SET OF WAVES
     • Wave front is perpendicular to the ray when wave front is talked about its a beam
   • On a wave diagram its the wave fronts that are shown not the waves
   • Length between wave fronts is the frequency

8. In phase- Molecules vibrate at the same time

9. Out of phase- Random out of order vibration
