When does the intensity of transmitted light become maximum when a polaroid sheet is rotated between two crossed polaroids?

The light transmitted reaches a maximum when the intermediate sheet has its direction of polarization at a 45 degree angle to both the outside sheets.

What is Distinguish between intensity and loudness?
the Decibel it measures the loudness and intensity
What is the relationship between wave amplitude and intensity?
I=a2
How is the intensity of a sound related to the distance between the source and the receiver?
The intensity of a sound will decrease according to an inverse square law.
What is the difference in light intensity between white and black?
Contrast Ratio
How does distance affect intensity of radiation?
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
What are the uses of polaroids?
Uses of PolaroidsBack to Top Polaroids polarize light. A number of needle shaped crystals quinine iodosulphate with their axes parallel to one another are packed between two sheets of plastic. This arrangement serves as the polaroids.The important uses are:These reduce excess glare and hence sun glasses are fitted with Polaroid sheets.These are also used to reduce headlight glare of cars.They are used to improve color contrast in old oil paintings.These are useful in 3-D motion pictures i.e., holography.Wind shields of automobiles are also made of Polaroid sheets.
What is the difference between the different polaroid spectra cameras?
The best place for information on the Polaroid Spectra cameras is camerapedia.org.
How did polaroid film form instant photos?
Polaroid film was instant film widely introduced in 1972. Polaroid film had chemicals in between layers and the film moved through rollers to initiate the developing after a photo was taken.
What is Distinguish between intensity and loudness?
the Decibel it measures the loudness and intensity
What is the price range for Polaroid digital cameras at Best Buy?
Including polaroid camcorders, the prices for polaroid digital cameras fall between thirty-six dollars to two-hundred-fifty dollars. This is the price range according to Best Buy's online store.
What is the difference between turbidimetry and nephelometry?
Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering.In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured.In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam.
What is Malus' law?
The Malus' law states that the intensity of the polarized light transmitted through the analyser varies as the square of the cosine of the angle between the plane of transmission of the analyser and the plane of the polarizer. Mathematically, it would be: I ∞ cos2θ or I = I0 x cos2θ.
Why polaroid sunglasses are better then ordinary sunglasses?
polarizing sunglasses have a specific grating on them that is usually vertical llllllllllll lllllllllllllll light can have various polarizations ... (this is the direction that the E and M fields go up and down) .... when something get's reflected ... say off of water It only is polarized horizontally ------- (that way if you like) ... since this light is polarized in the opposite direction as to the grating it cannot transmit ..... hence the glare off of objects is eliminated when you use polarizing lenses the intensity transmitted is I = I0 * cos^2(\theta) ... where theta is the angle between the lense grating and the light .... in this case it is 90 degrees so cos(90) = 0 and no light is transmitted for ordinary sunglasses .... the transmitted reduction is just uniform and effects like glare are not reduced any more or less than the direct sunlight
What is the relationship between amplitud and intensity?
I=a2
What is the relationship between magnification and light intensity of the field?
less light intensity gives a better vision
What year was the Polaroid Land camera serial G-100638 produced?
Polaroid has not released serial number information for most of their cameras, so it would be helpful if you specified a model. If the serial number corresponds with a Polaroid Model 80 Highlander (as it appears it may), the camera was made sometime between 1957 and 1962, possibly in the late 1950s.
What is the difference between Hockney's Photographic collages and his Composite Polaroid images?
There are some differences between Hockney's Photographic collages and his Composite Polaroid images. One difference is that the Composite Polaroid images are all broken up into equal size squares while the Photographic collages are broke up into rectangles. Another difference between the two is that the Composite Polaroid images all have the white boarder around each individual part of the whole image breaking it up to look like little frames while the Photographic collages have no boarder or edge allowing them to blend seamlessly. A final difference between the two is that the Composite Polaroid images do not over lap while the images that make up the Photographic collages do overlap in some places. These differences give each media it own unique quality.
