Light from an argon laser strikes a diffraction grating that has 5,500 grooves per centimeter. The central and first-order principal maxima are separated by 0.395 m on a wall 1.49 m from the grating. Determine the wavelength of the laser light. g

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?
