Sunlight is reflected off of a puddle of water ahead of a driver. the index of refraction of the water is 1.333. if a driver sits 1.5 m above the ground, at what distance from the driver will polarized sunglasses be most effective at blocking the reflected light from the puddle. hint: what angle does light become maximally polarized? 5. a. 1.1m b. 3.0m c. 2.0 m d. 0.75 m e. 2.5m

option C is correct

distance from the driver is 2 m

Explanation:

Given data

index of refraction of the water n = 1.333

driver height from ground=  1.5 m

to find out

What angle does light become maximally polarized and what distance from the driver will polarized

solution

we know that n1 for water = 1.33 and we know for air n2 = 1

so  tan(θ)  = n1 / n2

tan(θ)  = 1.33 / 1

so (θ) = 53.06 degree

so for distance d will be calculate as

tan ( 90 - (θ) ) = height / distance

tan ( 90 - 53.06 ) = 1.5 / distance

distance = 1.5 / 0.7519

distance = 1.994 m  = 2 m

so option C is correct

distance from the driver is 2 m

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
