Two linear polarizing filters are placed one behind the other, so that their transmission directions are parallel to one another. a beam of unpolarized light of intensity io is directed at the two filters. what fraction of the light will pass through both filters?
a.0.5 io
b.0
c.2 io
d.0.25 io
e. io

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
