A wave yra sin (wt - kx) on a string meets withanother wave producing

1.	A wave yra sin (wt - kx) on a string meets withanother wave producing a node at x = 0. Thenthe equation of the unknown wave is :(a) y= a sin (t+kx)(b) y=- a sin (t + kar)(c) y= a sin (wt - kov) elle(d) y=- a sin (wt - kox) Janwavepatten
Answer» let the other string eqn. be,y = asin(wt + kx)put x=0 in first wave eqn.we get,y = asin(wt)equate both,asin(wt + kx) – asinwt =0a(sin(wt +kx) – sinwt) = 0a cannot be zero. WE will get -a sin (wt+kx) -a Sin(wt+kt) is the right answer

Answer»

let the other string eqn. be,y = asin(wt + kx)put x=0 in first wave eqn.we get,y = asin(wt)equate both,asin(wt + kx) – asinwt =0a(sin(wt +kx) – sinwt) = 0a cannot be zero.

WE will get -a sin (wt+kx)

-a Sin(wt+kt) is the right answer
