Fall 2018: Calculating Properties of Waves

Frequency is defined as...

• Number of waves or cycles generated per second.
• The maximum displacement of a wave from its equilibrium position.
• The time interval between two consecutive waves.
• The distance between two identical positions on two consecutive waves.
