Objective The objective of this lab was to use standing waves in a resonance tube in order to measure the speed of sound. Standing waves were used due their constructive and destructive interference‚ which lead to nodes and antinodes in the wave.The nodes could be marked because they were silent‚ and the antinodes were loud. Hypothesis We expect to find a linear relationship between wavelength and period because the speed of sound is constant. The frequency will inversely change the wavelength
Premium Sound Frequency Wave
Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

CHAPTER-15 Question 15.1: * Answer (b) Answer: 10 MHz For beyond-the-horizon communication‚ it is necessary for the signal waves to travel a large distance. 10 KHz signals cannot be radiated efficiently because of the antenna size. The high energy signal waves (1GHz − 1000 GHz) penetrate the ionosphere. 10 MHz frequencies get reflected easily from the ionosphere. Hence‚ signal waves of such frequencies are suitable for beyond-the-horizon communication. Question 15.2: * Answer
