- Homework Statement
- Envision a wave of the form y(x,y)=100sin(2*pi*x - 4*pi*t) and locate two detectors to measure the disturbances at points x1 = 2 and x2 = 10. What will be the magnitude of the disturbance at the instant t' when y(x1, t') = 100.
- Homework Equations
- y(x,y)=100sin(2*pi*x - 4*pi*t)
Solving for t' by substitution I obtained t' = 7/8. Then I substituted x= 10 and t = 7/8 in the given equation. Is that the right way to do it? My answer key says the answer is 100 but I am getting 78.5.
