Sample Response: Personal water filters solve the
problem of having access to drinking water anywhere.
They are available and affordable. The materials used to
make them are durable. They remove bacteria but there
are still risks, because they cannot filter heavy metals or
viruses. Still, the benefits outweigh the risks.

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?
