A single slit of width 4.0 µm is illuminated by a sodium yellow light of wavelength 589 nm. Find the intensity at a 34° angle to the axis in terms of the intensity of the central maximum.

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
