Professor Dee is studying standing waves in his lab. He takes a tube open at one end that produces a standing wave with a fundamental frequency of 685Hz when the temperature is -5.00°C, what is the length of the tube in meters?

Two tubes of gas are identical and are open only at one end. One tube contains neon (Ne) and the other krypton (Kr). Both are monatomic gases, have the same temperature, and may be assumed to be ideal gases. The fundamental frequency of the tube containing neon is 475 Hz. What is the fundamental frequency of the tube containing krypton? The atomic masses are given by 20.180 u for neon, and 83.80 u for krypton. Number i Units

Oscillation of a 300 Hz tuning fork sets up standing waves in a string clamped at both ends. The wave speed for the string is 460 m/s. The standing wave has four loops and an amplitude of 2.5 mm. (a) What is the length of the string? (b) Write an equation for the displacement of the string as a function of position and time. Round numeric coefficients to three significant digits. I got 2.5sin(4.09x)cos(600pi*t), I think I'm close but I don't have it right.

A steel cable with total length 53 m and mass 120 kg is connected to two poles. The tension in the cable is 1,578 N, and the wind makes the cable vibrate with a frequency of 2 Hz. Calculate the wavelength of the resulting wave on the cable.

A music instrument is open only on one end. When a musician blows air in it, it is at the body temperature of 36C. If the musician places a finger to form a column of 20cm, what is the fundamental frequency of the sound produced? What is the wavelength of that sound wave?

A transverse wave travels across a string having a linear mass density 0.069 kg/m. The wavelength of the wave is measured to be 0.685 m and the frequency is 31.5 Hz. What is the tension in the string?

A flagpole consists of a flexible, 2.65 m tall fiberglass pole planted in concrete. The bottom end of the flagpole is fixed in position, but the top end of the flagpole is free to move. What is the lowest frequency fi of the standing wave formed by the flagpole, if the wave propagation speed in the fiberglass is 2730 m/s? fi = Hz

1. (a) What is the intensity in w/m of a laser beam used to burn away cancerous tissue that, when 90.0% absorbed, puts 540 J of energy into a circular spot 2.2 mm in diameter in 1.5 s? Hint: The laser is a collimated beam of light and does not produce a spherical wave. w/m? (b) Reflect on how this intensity compares to the average intensity of sunlight (about 1W/m) and the implications that would have if the laser beam entered your eye. Note how your answer depends on the time duration of the exposure. The intensity of a laser is about damaging if they enter your eye. times that of the sun, so clearly lasers can be very

A string has a length of 2.50 m and is fixed at the ends. At a frequency of 85.0 Hz, a standing wave with 5 loops is formed.   What is the wavelength of the wave when it is vibrating at the fundamental frequency of the wave? What is the fundamental frequency of the wave? At what frequency would the third overtone occur?

A steel cable with total length 57 m and mass 140 kg is connected to two poles. The tension in the cable is 1,981 N, and the wind makes the cable vibrate with a frequency of 2 Hz. Calculate the wavelength of the resulting wave on the cable.
