(II) A 6500-line/cm diffraction grating is 3.18 cm wide. Iflight with wavelengths near 624 nm falls on the grating, howclose can two wavelengths be if they are to be resolved inany order? What order gives the best resolution?
The figure shows an RC circuit. If the switch is connected to position A, what can you say about the voltage across the capacitor plates over time A) It is positive and increasing. B) The voltage is not changing – it is constant. C) It is negative and decreasing D) It is positive and decreasing. E) It is negative and increasing An RC circuit has a switch thrown so the capacitor is charging; after a long time the switch is flipped to position B. After this time, what direction is the current flowing in resistor R2 A) Upward B) To the right C) Counter-clockwise D) Downward E) None; no current flows. The figure shows an oscilloscope trace of a discharging capacitor. The settings are 2 V/div and 1.0 ms/div. Determine the time constant of this system. A) 14.5 μs B)
