1.The wave-related quantity algebraically equivalent to 1/f is Group of answer choices T λ ω A 2.When a sound wave moves through a medium such as air, the motion of the molecules of the medium is in what direction (with respect to the motion of the sound wave)? Group of answer choices 3. Which of the following ranges corresponds to the longest wavelengths? Group of answer choices all have the same wavelengths infrasonic ultrasonic audible 4. Waves propagate at 4.0 m/s along a stretched string. The end of the string is vibrated up and down once every 3.0 s. What is the wavelength of the waves that travel along the string? 5. A 2.0-m long piano string of mass 40 g is under a tension of 338 N. Find the speed with which a wave travels on this string. Group of answer choices 1040 m/s 520 m/s 260 m/s 130 m/s 6. A 5-m-long organ pipe is open at one end and closed at the other. Its fundamental tone has wavelength 7. The speed of sound at 0°C is 331 m/s. What is the speed of sound at 25°C? (0°C = 273 K) 8. If a guitar string has a fundamental frequency of 543 Hz, what is the frequency of its fourth overtone (fifth harmonic)?
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.
