Which two of the given transverse waves will give stationary waves when get superimposed

{z_1} = a\cos \left( {kx - \omega t} \right)

…(

A

)

{z_2} = a\cos \left( {kx + \omega t} \right)

…(

B

)

{z_3} = a\cos \left( {ky - \omega t} \right)

…(

C

)

View answer and explanation

Correct option: A

\begin{array}{llllllllllllllllllll} {A\,\,and\,\,B} \end{array}

Option A (A and B) is correct because stationary waves are formed by the superposition of two waves with the same amplitude and frequency traveling in opposite directions, which is the case with z1 and z2.
