1a,b
condition to represent progressiv waves =
must be bounded and of the form f(wt-kx)
first one has max 1/4 and min 0
second one u already know .
third one has max inf.
wich of these 3 (more than 1 crrct) represent progressive waves :
y = 1/(4 + (4t - 3x)2 )
y = sin(4t - 3x)
y = 1/(4t+3x)

21Hmmmm........
Yeah!! Okay So Bounded Max. & min. imply progressive Wave....... is it??
21Okay.........
So had 3rd been 1/(4t -3x)
It wud b considered progressive!!
1NO tapan!!!
the maximum value of third is infinity!!
and if we replace k by -k then we get the form in problem 3!!
so it is not that 4t+ 3x woudnt give a progressive wave
just that it is not bounded
21Oh okay!!!
Hope this time I am crrct :
So it means dat you find ∂Y/∂X and equate it to 0 and if the value of X we get is FINITE then the wave is said to b progressive.......... Is it??
Sorry For troubling U bro [2]
