1. How many wavelengths are shown in the standing wave pattern pictured below? 2. If the...
An electromagnet is used to create the standing wave pattern shown below. The string of 6 grams and a length of 150 cm. The tension in the string is created by the 250 gram hanging a) Determine the wavelength lambda of the travelling waves. b) Determine the speed of the travelling waves. c) Determine the frequency f and period of the travelling waves.
A standing wave pattern is created on a string with mass density u- 3x 10 kg/m. A wave generator with frequency f- 65 Hz is attached to one end of the string and the other end goes over a pulley and is connected to a mass (ignore the weight of the string between the pulley and mass). The distance between the generator and pulley is L- 0.74 m. Initially the 3rd harmonic wave pattern is formed. What is the wavelength...
Consider the standing wave pattern with 4 antinodes. This standing wave is on a wire of linear mass density 3g/m and length 2m. It is being driven by a magnetic vibrator on the end of the wire, wiggling the wire up and down at 120 Hz, find tension. The answer must be in Newton. The tension is now slowly increased, causing the standing wave pattern shown to disappear. At certain higher tension the next standing wave pattern appears. Tell how...
part 1. A 9.00-m long string sustains a three-loop standing wave pattern as shown. The string has a mass of 45 g and under a tension of 50 N. a. What is the frequency of vibration? b. At the same frequency, you wish to see four loops, what tension you need to use. Part 2. a. Determine the shortest length of pipe, open at both ends, which will resonate at 256 Hz (so the first harmonics is 256Hz). The speed...
Standing Waves in a Pipe - Both Ends Open Pattern (a) Pattern (b) Pattern (c) Pattern (d) The above figure shows standing wave patterns in a pipe whose left end is closed but the right end is open in all the patterns, the length of the pipe L = 2.10 m. The speed of sound in air is 343 m/s. You will find the wavelengths and frequencies of these standing wave patterns. (C) In Pattern (c), What is the wavelength?...
