Two transverse sinusoidal waves combining in a medium are described Y₁ = 5.00 sin z(x + 0.900t) Y₂ = 5.00 sin z(x - 0.900t) where x, y₁, and y₂ are in centimeters and t is in seconds. Determine the maximum transverse position of an element of the medium at the following positions. (a) x = 0.110 cm lymax= 0.060 X When two waves interfere the displacement of the medium at any particular position and time is given by the sum of the displacements due to the individual waves. cm (b) x = 0.440 cm lymax!= 0.241 X What is the function of x and t that is generated by writing the sum of these two waves? cm (c) x = 1.60 cm lymax=0.876 X You might consider making a rough sketch of the two waves at t = 0 and consider what happens to the sum of these two waves at the given value of x. cm (d) Find the three smallest values of x corresponding to antinodes. (Enter your answers from smallest to largest.) cm cm cm
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.
