    In a Kundt's tube filled with a gas at atmospheric pressure, a standing sound wave with a frequency of 1.40 kHz is generated. A maximum of the standing wave is measured at 56.2 cm and the next maximum is at 68.2 cm. What is the speed (in m/s) of sound wave in the tube? Lütfen birini seçin: O 344 O 712 O 178 O 336 O 172

  • A long cylindrical gas-tight tube, with a sound source at one end and sensor at the other

    1. A long cylindrical gas-tight tube, with a sound source at one end and sensor at the other, was constructed to measure the speed by recording the time it take a sound wave to travel the length of the tube (see diagram). i. Initially, the tube was filled with air at atmospheric pressure (P=1.012x105Pa & T=295.2K). When a sound wave is produced by the source, the elapsed time for the wave to reach the sensor was 3.64x10-3s. Determine the length of...

    A tube, open at the left end and closed at the right, has standing-wave patterns at frequencies of 198 Hz and 330 Hz. The speed of sound in air is 343 m/s. The lowest two harmonics (normal modes) that these two standing waves could be are m = and The frequency of the fundamental (m = 1) is Hz. The wavelength of the fundamental mode is m. The tube is m long

    12. A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. What is the fundamental frequency of a 2.50 m -long aluminum rod? The speed of sound in...

    A 0.75m long instrument tube has two open sides as a standing sound wave moves through it (speed of sound is 343 m/s). You count 4 nodes in the tube. (a) Find the wavelength and frequency. (b) You suddenly close both ends of the tube. The number of nodes doesn't change, but their positions do What is different about the air pressure and displacement? How did the wavelength and frequency change?
