Traditional incandescent light bulbs were used for many years and produce bright light, but the bulbs rapidly become too hot to
touch. Halogen bulbs are slightly more efficient. Compact fluorescent light bulbs (CFL) and Light-emitting diode light bulbs (LED)
generate less thermal energy. Based on this information, what types of bulbs are most likely indicated by the illustration
A)
incandescent and halogen
B)
incandescent and LED
halogen and CFL
D)
CFL and LED

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
