Among two interfering sources, let \( A \) be ahead in phase by \( 54^{\circ} \) relative to \( B \). If the observation be taken from point \( P \), such that \( P B-P A=1.5 \lambda \), deduce the phase difference between the waves from \( A \) and \( B \) reaching \( P \). 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
