Which statement correctly describes the relationship between a blackbody radiator, its temperature, and the electromagnetic radiation it gives off?
A. As the blackbody radiator becomes warmer, it reflects different
wavelengths of light.
B. As the blackbody radiator becomes warmer, it emits light of
shorter wavelengths.
C. As the blackbody radiator becomes cooler, it emits light of shorter
wavelengths.
D. As the blackbody radiator becomes warmer, it emits random
wavelengths of light.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
