An open organ pipe emits F (349 Hz ) when the temperature is 14 ∘C. The speed of sound in air is v≈(331+0.60T)m/s, where T is the temperature in ∘C. Part C What is frequency of the fundamental standing wave in the pipe? Part E What is the wavelength in the traveling sound wave produced in the outside air?

Problem 6. Electromagnetic plane waves in a lossy medium The electric field of an electromagnetic plane wave traveling in a lossy medium can be written as where z is the distance, t is time, and fthe frequency. For f 1 GHz, it is found by measurement that the amplitude of the electric field is attenuated by a factor of 3 after the wave travels 100 m (i.e., to 1/3 of the amplitude at z-0 when it arrives at z- 100...

In this homework, you will be using a sound simulation. We will demonstrate this simulation in class. If the simulation is too difficult to install on your computer, do not worry, you should still be able to answer the questions. It is important to know that a lighter shade of gray in the simulation indicates an increase in pressure compared to the undisturbed air pressure and a darker shade indicates an decrease in pressure. The simulation is available online from...
