Document Summary
No work need be shown and no partial credit will be given. (5 pts) 1. Unpolarized light with intensity 1 is incident on two ideal polarizers. The axis of the first polarizer makes an angle of 60 with the vertical and the axis of the second polarizer is horizontal. The intensity of the light after it has passed through the second polarizer is (a) 0. 1251o (b) 0. 375i (c) 0. 5001o (d) 0. 7501o (e) none of the above answers (5 pts) 2. A beam of light has a wavelength of 600 urn in a. material of refractive index. In a material of refractive index 1. 5 the lights wavelength will be (a) 300 urn (b) 450 rim (c) 600 nrn (ii) 700 rim (e) 800 urn (f) 1200 urn (g) none of the above answers (5 l)ts) 3. In the circuit shown in the sketch the voltage amplitudes for the resistor. inductor.
