In this post, i'll gave respond to the Mr. Albaini's post at www.interzone81.blogspot.com with my summary
So wave is where the individual parts of material always move in cyclical pattern.
There's 2 waves, it is:
"the particle displacement is parallel to the direction of wave propagation"
like when we shake a rope, and light wave.
"the particle displacement is perpendicular to the direction of wave propagation"
It's like when we stress a slinky and in sound wave. There's some other examples that i didn't understand.
And there's a:
Wavelength, is the lenght of a wave, determined by 1 phase and then back to the same phase.
Amplitude, is the height of the wave.
Velocity, is the speed of the wave.
Frequency, number of cycles in 1 second
Period, time taken for 1 cycle << addition from me
