When waves occupy the same space at the same time, the net wave is the SUM of the two wave amplitudes. This is best described as:

• Reflection

• Wave speed

• Interference

Harmonics occur when a frequency is specific to a ‘natural frequency’ of an oscillator, producing patterns. Based on the picture, which harmonic in the picture illustrates the greatest frequency?

• Fundamental

• 2nd Harmonic

• 5th Harmonic

• All have the same frequency
