Question Number 152346 by n0y0n last updated on 27/Aug/21
we know the equation of a simple harmonic wave  going to left to right is,   y=asin((2π)/λ)(vt−x)    if we put t=0 and x=0 ,  we get y=0  and if we put t=0 and x=0.25λ ,  we get y= a   !!  But How  could this be possible?  How could right side particles start oscillating  before the left ones?Don′t we need a   certain time gap  for right  side particles   to start oscillating??
