Fundamentals of Physics 10
In Fig. 35-39, two isotropic point sources S1 and S2 emit light in phase at wavelength l and at the same amplitude. The sources are separated by distance 2d ! 6.00l. They lie on an axis that is parallel to an x axis, which runs along a viewing screen at distance D ! 20.0l. The origin lies on the perp
