Answer:
Explanation:By using the sunglasses while looking at If your sunglasses are polarized, instead of only seeing the surface of a lake or river, you will suddenly be able to see through the glare and into the water below.
Another one is by comparing two sunglasses, hold your glasses and another one simultaneously and look through both pairs at the same time. Then, rotate one pair of sunglasses about 60 degrees. If both pairs of glasses are polarized, the overlapping area will darken as they filter out excess light. If your pair isn't polarized, however, you won't notice any difference.
Also it can be determined by simple computer test If you rotate your glasses sideways while looking at a computer monitor through polarized glasses, portions of your screen will become blank or go dark. The same also applicable to LCD display screens such as the ones on a gas pump.
Answer:
Fields and variables are proportional
Explanation:
To solve the problem we must first identify the Vector Intensity,
The intensity is given by:

We also know that the change given by the Intensity is always the square of the amplitude,
This is,

The intensity is <em>proportional</em> to the change exerted on 
That is to say that in turn the amplitus is <em>proportional</em> to the Intensity.
On the other hand, relating the two variables we have


In this way we can conclude that the electric field of intensity is also <em>proportional</em> to 
I think it's A.. could be wrong tho.
