WAVES

1. What are waves?
   Waves are disturbences that transported energy from one location to another location without tranportation of metal.
2. What are mechanical waves?
   Waves that require a material media to propagate from one point to another.
3. Why can waves propagate?
   Because they can propagate because of the the interaction forces between particles of a medium.
4. In the 'spring model', What do the springs represent?
   Spring represents the interaction forces between particles.
5. Can you specify two different types of mechanical waves?
   Transverse waves and longitudinal waves.
6. Can you define both kinds of waves?
   Transfer waves: they are waves which make the particles of medium vibrate perpendicular to the direction of wave motion.
   Longitudinal waves: waves make the particles of the medium vibrate parallel to the direction of the wave motion.
7. What is 'inertia'?
   Intertia is the tendency of objects to resist change in motion when are pushed or pull.
8. What kind of particles tend to have more inertia?
   Particles with greater mass tend have more inertia.
9. In longitudinal waves, are the particles of the medium carried along by the propagating waves?
   No they aren't.
10. In longitudinal waves, why don't the particles of the medium move at the same time?
    Because they have inertia.
