Questions
A wave motion has the function . The graph in figure shows how the displacement y at a fixed point varies with time t. Which one of the labelled points shows a displacement equal to that at the position at time t = 0
detailed solution
Correct option is B
At t = 0 and x=π2k. The displacementy=a0sin ω0−k×π2k=−a0sinπ2=−a0from graph. Point of maximum displacement (a0) in negative direction is Q.Talk to our academic expert!
