Please kindly help me.
Actually I don't quite understand what the meaning of harmonic wave is and the mathematics that expresses it.
h(x,y;t) = h sin(wt-kx+δ)
h represents the position of the particle in a particular time? Or the wave motion?
What is the physical meaning of w, k? What are they describing? Why the function is written as h sin(wt-kx+d)?
Can you explain that? My mathematic is not very good, to be honest.
1) What is the distance between two maxima/minima in an interference pattern of two waves u1 and u2 described by
u1(x) = cos(k1 x); u2(x) = cos(k2 x)
What happens when k1=k2?
2) "The so-called nami-water is good to our body!" Is the statement scientific (falsifiable), and why?
The Attempt at a Solution
The distance between two maxima/minima in an interference pattern = the interfered wave's wavelength?
