phase

Question 1

what is phase

Answer 1

is a measurement of the position of a point along the wave cycle

Question 2

what is phase measured in

Answer 2

in angles (degrees or radians) or in fractions of a cycle

Question 3

One full cycle (1 wavelength λ) is

Answer 3

= 360࿁
= 2π radians

Question 4

where is phase difference

Answer 4

its between two particles vibrating at the same frequency is fraction of a cycle between the vibrations of two particles

Question 5

in phase

Answer 5

when both waves are at the same cycles stage (crests line up with crests; troughs line up with troughs)phase difference of 0࿁ (0 rads)

Question 6

out of phase

Answer 6

when one wave is shifted relative to the other (crests and troughs do not align) phase difference between 0࿁ and 180࿁ (between 0 and π rad )

Question 7

Completely out phase

Answer 7

when the crest of one wave meets the trough of another wave. This happens when they are half a cycle apart, corresponding to a phase difference of 180࿁ or π rad
