Goid evening friends...
Sound, music and music are the words without which the life of everyone is incomplete, it has the same importance in everyone's life as much as our lives are of colors, As life without color is faded, even without Suro, life seems incomplete.
When someone shouts"hello", billions of molecules push and shove through the crowded air between you, speeding the sound to your ears. If we could watch this happen,we'd see that sounds are waves of energy that squeeze and stretch the air as they travel.
All sounds travel in waves, and what makes one sound different from another is simply the shape of its waves. unlike waves on water, which snake up and down as they move forward, sound waves push and pull in the same direction that they travel.
Sound is ultimately just another type of energy, like light or heat,but it's special to us because it carries words and music at high speed. without sound we wouldn't be able to listen to birds singing in the trees or the latest pop songs on the radio.it has the ability to affect our emotions and stir up our interest in the world around us.
speed of sound.....
We see lighting flash several seconds before we hear thunder claps, because light travels much faster than sound.at ground level,at an air temperature of about 20°C, sound travels at 343 m.per second.
Musical sound....
Our brains instantly spot the difference between noise and music. Musical notes are made from sound frequencies connected in precise ways. if you play the eight notes in an octave, the highest has exactly twice the frequency of the lowest, you make complex waves that have the same frequency but different shapes.
