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.
