A source and a detector move away from each other in absence of wind with a speed of \(20 \mathrm{~m} / \mathrm{s}\) with respect to the ground. If the detector detects a frequency of \(1800 \mathrm{~Hz}\) of the sound coming from the source, then the original frequency of source considering speed of sound in air \( 340 \mathrm{~m} / \mathrm{s} \text { will be ..... Hz. }\) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
