Consider the equation y(x,t)=Acos(at)sin(bx)y(x,t)=Acos(at)sin(bx) Let x represent some position and t represent time.

Part (a) Describe a physical situation that could be represented by this equation. As part of your description include a sketch and a written description. Indicate what y and x correspond to in the situation you describe. Part (b) How, if at all, would the physical situation you described in part A be different if a were twice as large? Explain how you determined your answer. Part (c) How, if at all, would the physical situation you described in part A be different if b were twice as large? Explain how you determined your answer.
