Only 25% of the intensity of a polarized light wave passes through a polarizing filter. What is the angle between the electric field and the axis of the filter?
The formula E = IZ, where E represents voltage, I represents current, and Z represents impedance (a measure of opposition to a sinusoidal electric current), is used in electrcal engineering. Each variable is a complex number. Use the formula to find the missing quantity for the given conditions. Then convert the given conditions to trigonometric form and check your result.
