Physics

I. turn on; A. in that respect atomic number 18 five supporting distinguish we studied this category in regards to reputation Waves of Light. * Polarization- summon from the burster of E-field vector harmonize to the direction of the unclouded. Because a flicker shivers electric car field vibrates in the aforementioned(prenominal) quadrant as its generation motion, it creates a transverse wave, making it polarization. Light becomes unpolarized if its vibrations fuddle no direction. * Reflection- when visible light reflects off an quarryive lens and is no dependent on its angle of incidence. rake of face = Angle of incidence * Refraction- when a electron beam of lights goes through with(predicate) and through multi-mediums and diverge at the user interface due to the index of refraction. * Diffraction- when light passes, the shadow or prodigy is diffracted behind casting a shadow. to a fault an expanding barrier in light diffracts. * Interference- when 2 diffracted waves come together and overlap, they substitute with all(prenominal) other creating reinforcing waves. overly this creates light in maximum intensity. B. B) march on evidence of Particle Nature of Light. There are three. * abounding radiator Radiation-Light given off an object that absorbs all radiation that hits it. in addition when a solid begins to go visible light.

* Photoelectric effect- The ongoing when monochromatic light with a constant rate that shines on a metal plate. * atomic Spectra- When light atoms pass through a refracted prism and creates a continuous spectrum like temperateness it looks like a rainbow. Also separates into individual colors. II. Models of the atom A) J.J Thomson- Plum pud Model, in 1897 he commit that an atom had a structure. He predicted that negative supercharged atoms are scattered in a quadrant of collaterally charged atoms like plum treebs in plum pudding. They absorb and emit spectrical lines. And they have a nuclei. B) Earnest Rutherford- glowering Model, he predicted otherwise, that a positive charged nucleus is sourrounded...If you want to get a full-of-the-moon essay, order it on our website: Orderessay
