60°
30°
90°
What do light waves do as they pass from one transparent material to another?
bend

Polarized sunglasses work so well because most glare is already polarized in one direction. why is the glare polarized horizontally?
because polarized light is brighter
because the sun is hitting a horizontal surface and all the scattered light that is reflected is bounced in a way that matches that horizontal surfacce
because the glare knows the sunglasses are polarized vertically
Polarized sunglasses are a scam
polarized light is a beam of light where all the separate light waves have which of the following in common?
the speed of the light
the color of the light
the phase of the light
the orientation of the electric field of the light
the amplitude of the light
the frequency of the light
Watch this video on 3d holograms
Do you have any questions?
yes
no
coherent light is a light beam where all the light waves have which of the following in common?

the amplitude of the light
the orientation of the electric field of the light
the color of the light
the phase of the light
ok, light week this week, you are to spend the majority of your astronomy time writing and researching for the quest.
what is polarized light
why does reflection cause glare
why do sunglasses reduce glare so much more than regular light
how do polarizers work
What is the difference between coherent light and polarized light
