A Transverse Periodic Wave Is Represented by the Equation Y(x,t) $\omega$

question 34

Multiple Choice

A transverse periodic wave is represented by the equation y(x,t) = A1 sin( $\omega$ t - kx) .Another transverse wave is represented by the equation y(x,t) = A2 sin( $\omega$ t + kx) .What is the equation that represents the superposition of the two waves?

• A) y(x,t)= (A1+A2)sin(\(\omega\)t)cos(kx)+ (+A1+A2)cos(\(\omega\)t)sin(kx)
• B) y(x,t)= (A1+A2)sin(\(\omega\)t)cos(kx)+ (-A1-A2)cos(\(\omega\)t)sin(kx)
• C) y(x,t)= (A1-A2)sin(\(\omega\)t)cos(kx)+ (-A1+A2)cos(\(\omega\)t)sin(kx)
• D) y(x,t)= (A1+A2)sin(\(\omega\)t)cos(kx)+ (-A1+A2)cos(\(\omega\)t)sin(kx)
