Wave Problem Solving 1. Awavegenerator produces 20 pulses in 5 seconds Calculate the period and frequency of these pulses. Period, Frequency, 2. When finding relationship between frequency and the length tube needs tobe to make the sound loud, atubeispartially submerged it water so that the botton end of the thei the water while thetopendstyysopen Ifthe speed of soundi 340m/s what wouldbe shortes length oftube neededts make 494 Hztuning fork sound louder? L 3. Apanicular organ pipe is OPEN on both ends What the shortest length the tube wouldneed frequency of 260 Ha would sound louder ?Use 343mis for speed sound air (What anount the wavelengeh would the tube be?)
