Waves: Properties of a wave.

Question 1

What is the amplitude?

Answer 1

• Maximum displacement of a point on a wave away from its undisturbed point.

Question 2

What is the wave length?

Answer 2

• Distance from a point on one wave to the equivalent point on the adjacent wave.
• Wave Length Longitudinal wave: From one compression to the next compression or from one rarefraction to the next rarefraction,

Question 3

What is the frequency?

Answer 3

• Number of waves passing a point in each second.
• Units: Hertz. (HZ).
  1 Hz= 1 wave per second.

Question 4

What is period?

Answer 4

• Time in seconds for one wave to pass a point.

- Period= 1/frequency.
