Pendulum Conclusion.

Wave are oscillations (repeating disturbance or movement) that transfers energy through matter or space. Wave- energy transfer due to the movement due.

What is a wave? Speed, wave length and frequency

One vertical Pulse Direction of wave propagation Direction of oscillation = transverse wave Waves on strings

One horizontal Pulse Direction of propagation Direction of oscillation = longitudinal wave Compression waves sound

Reflection at a fixed end Reflected pulse is inverted

Reflection at a loose end Reflected pulse is not inverted

Wave motion Displacement versus time at fixed position time period y

Wave motion Stop! Snapshot at a fixed time. Distance between equivalent points on the wave = wave length The wave travels a distance of one wave length in the time of one period

Speed of the wave Speed = Distance Time = Wave length period
