Q1: A student observing the ocean notes that n = 9 crests break in t = 4.8 minutes Part (a) Input an expression for the frequency of the waves. Part (b) What is the frequency in hertz? Q2: Suppose a diving board with no one on it bounces up and down in a simple harmonic motion with a frequency of 4.25 Hz. The board has an effective mass of 12.5 kg. What is the frequency, in hertz, of the simple harmonic motion of a 71.5-kg diver on the board?
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.
