amplitude?

7. anonymous

ik but d. was rong

D. frequency. is wrong

9. Michele_Laino

I think position, since a plane wave can be represented by this formula: $\Large f\left( {x,t} \right) = A{e^{ - \left( {kx - \omega t} \right)}}$ where x is the position, and t is time

oops.. $\Large f\left( {x,t} \right) = A{e^{ - i\left( {kx - \omega t} \right)}}$
