Homework Statement
Assume that the waves from the sources are emitted in phase, and that at the point P, amplitude of the disturbance is zero. what is the wavelength of the traveling wave emitted by the sources? (there is more than one possible answer here,but provide the largest possible wavelength.)
Known:
r1=15.4cm
r2=16.2cm
d=1.8cm
θ=26.3°
Homework Equations
Δr=nλ
The Attempt at a Solution
maximum wavelength, n=0
Δr=|16.2cm-15.4cm|
=0.8cm
I am lost, please help me.
