Question 4 CXNYC-Problem-Set-...NYC formula_sheet_...ஆ05-InterferenceTNYC-Midterm-Review...BELTPROBLEMQuestion 4:A speaker fixed to a moving platform moves toward a wall,emitting a steady sound with a frequency of 230 Hz. A personon the platform right next to the speaker detects the soundwaves reflected off the wall and those emitted by thespeaker. How fast should the platform move, Vp, for theperson to detect a beat frequency of 5.00 Hz? Take the speedof sound to be 344 m/s.Question 5:A trumpet player hears 5 beats per second when she plays anote and simultaneously sounds a 440 Hz tuning fork. Afterpulling her tuning valve out to slightly increase the length ofher trumpet, she hears 3 beats per second against the tuningfork. Was her initial frequency 435 Hz or 445 Hz?a.435 Hz, since the beat frequency did, in fact,decrease.b. 445 Hz, since the beat frequency did, in fact,decrease.C.445 Hz, because if she was playing above thetuning fork frequency, increasing her frequencywould bring her closer to the frequency of thetuning fork, which would decrease the heat

Question (4):The frequency emitted by the speaker is Beat frequency is Speed of sound is Find:Speed…
