progressive wave definition
an oscillation that travels through matter (or a vacuum).
what do all progressive waves do
transfer energy from one place to another, but not matter
what happens when progressive waves travel through a medium
the particles move from their equillibrium position to a new position, the particles exert a force on each other.
whats a restoring force
when a displaced particle is pulled back to its original position
whats a transverse wave
oscillations of the particles are perpendicular to direction of energy transfer
whats a longtudinal wave
oscillations of the particles are parralel to the direction of energy transfer
wavelength definition
minimum distance between two adjascent point oscillating in phase
amplitude meaning
maximum displacement from equillibrium position
peak and trough definitions
peak- maximum positive displacement from equillibrium
through-maximum negative displacement from equillibrium
equilibrium definition
resting position for particles in a medium1`
