During one oscillation, phase of oscillation changes by _____?

ایک دوہری کے دوران ، _____ کے ذریعہ دوئم کے مرحلے میں تبدیلی آتی ہے؟

π⁄2 rad

π rad

2π rad

None of these

In one complete oscillation (one full cycle), the phase of an oscillating system changes by $2pi$ radians.

This corresponds to the system returning to its starting position in a periodic motion, such as simple harmonic motion.
