Consider two electromagnetic waves, $\vec{E_1}$ and $\vec{E_2}$: $\vec{E_1} = 2E_0e^{i(kx-\omega t+\pi)}\hat{j}$ $\vec{E_2} = E_0e^{i(kx-\omega t)}\hat{j}$ If the waves are traveling in the same space at the same time, which of the following is true? The waves are 90 degrees out of phase. The waves will interfere destructively. The waves are propagating along the y-axis. The electric field is oriented along the x-axis.

6. Crude oil with density $\rho$ and viscosity $\mu$ flows steadily down a surface inclined $\theta$ below the horizontal. The velocity profile in the film is given by $u(y) = \frac{\rho g}{\mu} \left[ hy - \frac{y^2}{2} \right] \sin \theta$. Determine the magnitude and direction of the shear stress that the oil exerts on the fixed surface.
