What else can I help you with?
How can you tell if electric sunglasses are polarized?
because they are green
How can you tell if a pair of sunglasses is polarizing or not?
To tell if your sunglasses are polarized, look for a polarization label or try this simple test: glance at a reflective surface, like water or a car window, and then rotate your glasses 90°. If the glare fades or disappears, they’re polarized.
Does ultraviolet light look purple to the human eye?
It doesn't look anything. The human eye can't see it at all. You can't even tell if ultraviolet light is there or not.
How can you tell if glasses are polarized?
To see if your glasses are polarized, look through them and tilt them at different angles. If they get darker or change color, they’re likely polarized. You can also check for a label on the lenses that says polarized.
When unpolarized light is polarized what happens to light waves that exist at say 45 degrees to vertical?
Asumming the polariser is vertical, then 100% of vertically polarised light passes through it and 0% horizontal light passes through it. Simple so far. For 45 degree light it gets weired. Each photon of light has a 50:50 chance of making it through. It is impossible to tell if a particlular photon will or will not pass through. it is totally random. If it does pass through however it will change its polarisation to vertical! So a scientist would measure a beam of vertically poloarised light at 50% intensity.
Where to get uv light bulbs?
UV lamp, also called Black-light Lamp, device for producing electromagnetic radiations in the wavelengths between those of visible light and X-rays. The Sun's rays are rich in such radiation, sometimes referred to as black light because it is not visible to the unaided eye.
What makes light so important?
You can tell how big a star is using light and you can tell what elements it is made from using light.
are you human?
are you, tell meeeeee!!!!!!
How do you tell if sunglasses are polarized?
If they're on a rack with others, take two pair and hold them the same like you're looking through both, and then look through both lenses at once. Then rotate one pair of glasses through 90 degrees. You should have gone from seeing through both darkened lenses to not being able to see anything at all through them. Assuming they're all by themselves - found in the bottom drawer, or on a park bench - hold them up and look at the blue sky through them. Rotate the lenses. The sky should brighten and darken through polarized lenses. Bees use the polarization of sunlight to help them navigate. Alternately look at a digital display on a watch or other equipment through the lens (Not LED display). Rotate the lens the display will go black at part of the rotation (The display has a sheet of polarized material - reducing this solution to the first answer)
What is stronger human tongue or human bicep?
couldn't tell ya
Who is the first human to fast?
It is not possible to tell who was the first human to fast.
Can a Picses human tell the future?
No
