The speaker and two microphones shown in the figure are arranged inside a sealed container filled with neon gas. The wires from the microphones are connected to an oscilloscope (not shown). The signal from the microphones is monitored beginning at time t = 0 s when a sound pulse is emitted from the speaker. The pulse is picked up by microphone 1 at t1 = 1.150 × 10-2 s and by microphone 2 at t2 = 1.610 × 10-2 s. What is the speed of sound in neon gas?
