Question 1

What is a period

Answer 1

Time it takes to complete one cycle of vibration.

Question 2

Frequency

Answer 2

Number of cycles per second

Perceived as pitch

Question 3

Amplitude

Answer 3

Magnitude of vibration determined by the displacement of air particles
Perceived as loudness

Question 4

Relationship of period and frequency

Answer 4

As period decreases, frequency increases

Question 5

Complex waveforms

Answer 5

Combination of sine wave of different frequencies and amplitude phases.

Question 6
