The bending or spreading out of a wave at an obstacle or at the edges of an opening is called diffraction. (Sine-1/d) The amount of diffraction, (for all wave types) depends on the wave's wavelength A and the relative size of the opening d. If the speed of sound is 343 m/s and the speed of light is 3x10^8 m/s. What would be the ratio of the size of an opening to give the same amount of diffraction for sound and light? Take the frequency of sound at 500 Hz and light at 5x10^14 Hz ratio (Aiight /Asound = dlight/dsound) Over a million times smaller O b. Over a hundred times smaller O c. Over a thousand times smaller O d. Over ten times smaller
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.
