We want to build a flute with two open ends. We want to flute to produce a sound of 388 Hz (fondamental). To do this, we take as a reference the sound of a tuning fork having exactly this frequency. After making the flute, we realize that the sound is not right. When listening to the flute and the tuning fork at the same time, we hear the following sound represented on the picture below. The speed of the sound in the flute is 331 m/s. How much to we need to reduce or increase the length of the flute for it to be in tune with the tuning fork ?

A sound wave enters the thin tube at P and exits at Q. Assume r = 0.41m and the wavelength is 1.86m. What is the smallest length d that results in destructive interference at Q?
In each of the four scenarios shown in the images, a large bat lets out a short burst of ultrasonic sound, which a smaller bat hears a moment later. If the large bat flies at 2.320 m/s and the small bat flies at 13.80 m/s, order the frequencies that the smaller bat detects in the four scenarios from highest to lowest. Assume that the speed of sound is 343.0 m/s. Highest frequency A D B. A B C Lowest frequency Answer Bank In Scenario C, part of the large bat's signal reflects off the small bat and returns to the large bat, warning it of the smaller bat's presence. If the initial signal has a frequency of 66.70 kHz, what return frequency fr will the large bat detect? Calculate the final frequency to four significant figures. fr Incorrect kHz Ꭰ
Two loudspeakers on a concert stage are vibrating in phase. A listener is 52.5 m from the left speaker and 24.0 m from the right one. The listener can respond to all frequencies from 20 to 20 000 Hz, and the speed of sound is 343 m/s. What are the two lowest frequencies that can be heard loudly due to constructive interference?
