$y_1=sin(x-2t),$ and $,y_2=sin(\frac{x}{2}2t)$

Multiple Choice $0\mathrm{.}2$ points

Which of the following expressions accurately describes how these two distinct waves will combine? We call this interaction the principle of superposition.

$y_1{y}_2=sin(x-2t)sin(\frac{x}{2}2t)$

$y_1{y}_2=sin(x-2t)sin(\frac{x}{2}2t)$

$y_1{y}_2=sin(x-2t\frac{x}{2}2t)=sin(\frac{3x}{2})$

$y_1{y}_2=sin((x-2t)(\frac{x}{2}2t))=sin(\frac{{}^2{x}^2}{2}{}^{2}xt-4{}^2{t}^2)$
