the wave equation

• the period of the wave is the time taken for particles in a medium to complete one cycle of vibration and is measured in seconds
• the frequency of the wave is the number of complete cycles in one second and is measured in hertz
• speed or velocity of wave is the measure of how fast the wace propagates through a medium
• wave speed is the distance a wave travel per second
• the speed of the waves depends on the medium that the wave travel through
• speed of the wave: wave length / period
