chapter 7

the color fo an object depends on?

which wavelengths of light shine on the object an dwhich wave engths are reflected

the leaf is green because?

the primary pigemnt in the plant refelects green light

subtractive primary colors?

filter out all light when combined

when blue light and yellow light are combined? what if its pigments not light?

white light ocures, if ists pigment color green would ocure

linear polarization?

how does unpolaruzed form and how does linearly polarized form?

the aligmnet of elecromagnetic waves in such a way where vibrations of electric fields in each of the waves are parralel to eachother

randomly oscilating electric fields

light waves with aligned electric fieds are lineearly polarized

polazization of natural light is formed by?

transmission reflection and refraction

another way to produce polarized light is? what are all the ways again?

scattering , relfection refraction and transmision

scattering?

the absorbtion of light by atmospheric particles so that its radiated again

pigments can be made by? light of diffrent colors also? primary subtractive? additive?

combining subtractive colors , by combining additive colors

rpoduces white light , may filter light

Polarization of loght by?

Scaterring produces a partially or totally polarized light
