Wave phase phase The phase of a wave refers to a position in its cycle, it indicates the wave's progress, Or a certain position in its cycle. It indicates specific point in its cycle and how far it has progressed through a complete oscillation It is measured in degrees or radians
Wave phase phase Representing phase of a wave using radians: In degrees In radians 0 0 90 1/2 180 270 3/2 360
Wave phase phase Representing phase of a wave using radians: In degrees In radians 0 0 90 1/2 180 270 3/2 360
Wave phase phase Representing phase of a wave using radians: In degrees In radians 0 0 90 1/2 180 270 3/2 360
Wave phase phase Exercise: convert the following to radians (450 , 720 , 1440 , 120 , 60 , 45 ) Radians = Degrees Multiply by , then divide by 180 180
Wavefronts Wavefronts are described as lines that represent points in the same phase on a wave and are often used to illustrate how waves propagate through space
Wavefronts Wave superposition When two waves meet, their vectors are summed Waves can interact constructively, with a larger sum wave The waves are said to be in-phase Waves can interact destructively, with a lower/cancelled sum wave The waves are said to be in anti-phase (180 degrees or ) apart
