Mr. Alba's post


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:

Transverse Wave

"the particle displacement is parallel to the direction of wave propagation"
like when we shake a rope, and light wave.

Longitudinal 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
