A steel piano wire is 60cm long and has a mass of 3.0g. If the tension in the wire 550 N, what are the fundamental frequency and the wavelength?

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 2.0-m cable under tension has a 12-kg mass. a standing wave of frequency 10 Hz has a wavelength of 0.40m. what's the cable's tension (in N)?

A 0.500-m string is clamped at both ends. If the lowest standing wave frequency in the string is 300 Hz, what is the wave speed?

A thick power line of length 75 m is stretched taut between two poles, experiencing a tension force of 6250 N. The mass of the power line 750 kg. What is the maximum resonate frequency of the cable if the wavelength is exactly 1/3 the length of the cable?

An interface is formed between a block of aluminium (with an acoustic impedance of 1.8 x 107 kg m2 s') and a block of copper (with an acoustic impedance of 4.6 x 107 kg m-2 s-1). Longitudinal sound waves travelling through the aluminium are normally incident on the boundary, and are partially reflected. a) What is the ratio of the amplitude of the reflected wave to that of the incident wave? Number b) What is the ratio of the amplitude of the transmitted wave to that of the incident wave? Number c) What percentage of the incident power is transmitted? Number d) What percentage of the incident power is reflected? Number % Ouit P Sove Questi

A string is connected to an oscillator and then laid horizontally, with the other end draped over a pulley and a mass of 200g is hung from that end. The string is found to have a mass of 15g and a length of 1.2m. The oscillator is turned on and the frequency is tuned until a standing wave is seen. You see 6 full wavelengths along the 1.2m length of the string. The oscillator frequency is set to 63Hz. What is the speed of the wave on the string based on your measurements? Give your answer in m/s and to 1 decimal place.

A transverse wave travels across a string having a linear mass density 0.065 kg/m. The wavelength of the wave is measured to be 0.71 m and the frequency is 52.5 Hz. What is the tension in the string?

A violin string with mass 0.35g is 35cm long. The frequency of a wave supported by the string is 196hz.  a) Assuming that this wave is a findamental frequency, what is the speed of the wave? b) What's the linear density of the string? c) Whats the tension in the string?
