Phase and Phase difference

Question 1

How are the positions in a wave presented?

Answer 1

In radians or degrees on a sine wave

Question 2

How do you find the phase difference between two points on the same wave?

Answer 2

Find the difference in phase between the two points

Question 3

How do you determine the phase difference between two waves?

Answer 3

Method 1:
* choose a point
* draw a vertical line
* find the phases of the wave on each point and find the difference
Method 2:
* Δbetween two points of a wave in phase/λ x 2π
