Question

Can anyone give me basic idea for wavelength, amplitude, pitch, volume, loudness etc.

Answer 1

I presume you are talking about sound..

sound is a wave.. more or less like ripples of waves you see in water when you drop a stone.. but the difference is.. in water, the water particles move up and down while the the wave travels forward (like a mexican wave in football :D.. how hands move up and down but the wave moves right or left).. so wave motion is perpendicular to the particle motion..

but sound wave is different .. it has particles waving in the same direction as that of the propogation itself..

ok when you have a wave.. you can select a portion of the wave and just keep repeating it over and over again to produce the same entire picture.. that portion is called the wavelength.. its essentially the length of one wave..

Answer 2

Amplitude:

when you drop a stone .. you see ripples.. if you drop the stone from a higher distance you ll see bigger ripples more pronounced ripples... why? cause now the particles are oscillating to more.. they are waving up and down more.. that is called the amplitude..

so in the above figure.. the top one has a smaller amplitude, the second one the bottom one.. has a bigger amplitude.. so its the max distance from the mean position that the particle oscilates.. its the same with sound.. just that the particles now oscillate parallel to the wave motion... its difficult to draw that thou
