Question

please ans this...with reason is formed​

Answer 1

Answer:

the answer is 2nd option

wave traveling along positive x axis is

y1=Asin(kx-omega t)

put x=0

y1 =-asin(wt)

wave traveling on negative x axis

y2=-asin(kx+wt)

put x=0

y2=-asin(wt)

super imposed y=y1+y2

y=-2asin(wt)

negative indicate minimum amplitude

so the answer is antinode
