They have a resistance Ω 200−Ω200Omega200, an inductor 0.400 H and a capacitor 6.00−μF6.00mu F6.00−μF. Suppose you take resistance and inductor and create a serial connection with a voltage source with a voltage amplitude of 30.0 V and an angular frequency of 250 rad/s. a) What is the impedance of the circuit? (b) What is the current amplitude? c) What are the voltage amplitudes at resistance and inductance? (d) What is the phase angle ΦPhiΦ of the source voltage with respect to the current? Is the source voltage lagging behind the current or is it leading? (e) Create the phasor diagram. A Michelson interferometer uses light from a sodium vapour lamp. Sodium atoms emit light with wavelengths of 589.0 nm and 589.6 nm. The interferometer is first constructed with the two arms of equal length (L1=L2)left(L_{1}=L_{2}right)(L1=L2), creating a bright spot in the middle of the interference pattern. How far should the mirror M2mathrm{M}_{2}M2 be shifted for one wavelength to produce a new maximum greater than the other wavelength?
