An ac circuit consists of an ac voltage source, a resistor, and an inductor. An object is placed a distance s to the left of the convex surface of a spherical mirror. The image is (a) upright (b) inverted (c) the orientation of the image depends on s (5 pts) 4. Unpolarized light with an original intensity 1o passes through two ideal polarizers. The axis of the first polarizer is vertical and the axis of the second polarizer makes an angle of 600 with the vertical. The intensity of the light after passing through both polarizers is (a) io (b) !io (c) io (d) (e) zero (5 pts) 5. A light beam has a wavelength of 200 urn in a material of refractive index 4. 00.
