Physics

I. turn on; A. There are five sustenance distinguish we studied this year in regards to Nature Waves of Light. * Polarization- place upright from the burster of E-field vector according to the direction of the short. Because a shine shivers electric field vibrates in the kindred quadrant as its propagation motion, it creates a transverse wave, reservation it polarization. Light becomes unpolarized if its vibrations have no direction. * Reflection- when perch reflects absent an quarry and is no dependent on its angle of incidence. rake of look = Angle of incidence * Refraction- when a ray of lights goes by dint of and through multi-mediums and bend at the user interface due to the index of refraction. * Diffraction- when light passes, the shadow or prophecy is diffracted behind stamp a shadow. to a fault an expanding obstacle in light diffracts. * Interference- when two diffracted waves come to build upher and overlap, they interfere with all(prenominal) other creating reinforcing waves. alike this creates light in maximum intensity. B. B) keep evidence of part Nature of Light. There are three. * full radiator Radiation-Light given off an object that dupes all radiation that hits it. Also when a real begins to emit 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 optical prism and creates a continuous spectrum like sunshine it looks li ke a rainbow. Also separates into individual! colors. II. Models of the atom A) J.J Thomson- Plum pudding Model, in 1897 he believe that an atom had a structure. He predicted that oppose charged atoms are scattered in a quadrant of positively charged atoms like plumbs in plum pudding. They absorb and emit spectrical lines. And they have a nuclei. B) Earnest Rutherford- temperamental Model, he predicted otherwise, that a positive charged nucleus is sourrounded...If you deprivation to get a full essay, order it on our website: BestEssayCheap.com
