Question

1)An R-C circuit is driven by an alternating voltage of amplitude 110V and frequency ?. Define Vout to be the amplitude of the voltage across the capacitor. The resistance of the resistor is 1000ohms , and the capacitance of the capacitor is 1.00uF.What is Vout if ?=10radians/s?What is Vout if ?=105radians/s?

2)Find the frequency of electromagnetic wave with wavelength of 1.0cm .Find the frequency of electromagnetic wave with wavelength of 660nm .Find the frequency of electromagnetic wave with wavelength of 1.4fm .

Explanation / Answer

2)

1 cm = 1 x 10^-2 m

Substitute into ?? = c:

(1x 10^-2 m) (x) = 3.00 x 108 m s
