Homework Statement
In a large water tank experiment, water waves are generated
with straight, parallel wave fronts, 3.00 m apart. The
wave fronts pass through two openings 5.00 m apart in a
long board. The end of the tank is 3.00 m beyond the board.
Where would you stand, relative to the perpendicular
bisector of the line between the openings, if you want to
receive little or no wave action?
Homework Equations
xn represent the horizontal distance between the perpendicular bisector drawn to the line joining the two sources and the nth nodal line
λ=(Xn/L)(d/n-0.5)
Answer is 1.25m
The Attempt at a Solution
λ=3.0m
L=3.0m
d=5.0m
I got stuck since i don't know which nodal line(n)
