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

A number of amusement parks have rides that make vertical loops like the one shown in Figure 6.33. For safety, the cars are attached to the rails in such a way that they cannot fall off. If the car goes over the top at just the right speed, gravity alone will supply the centripetal force. What other
