Question

draw a wave and indicate points which are in phase,out of phase ,have a phase diffrence of π2​

Answer 1

Answer:

Explanation:

In the pictures of 3 different waveforms; the A and -A states the amplitude of the wave at positive polarity and the negative polarity repectively.

t states the time at the x axis of the waveform. The figure 1 shows the difference between two waveform is π/2.

The figure 2 shows the out of phase of two waves.

And the figure 3 shows the in phase of two waveform. The amplitude might be different but the phase of the waveforms are same or in phase.
