Document Summary
Lecture 3: october 13, 2014: optical phenomena: scattering is a deflection of light due to reflection into different directions; ex: a cloud. The three different types of scattering are rayleigh, mie, and geometric. The differences of scattering come from the sizes of scatters with respect to light wavelengths (0. 4-0. 7 m) The various types of scattering of visible light. I is rayleigh scattering: rayleigh scattering is when air molecules scatter the shorter visible wavelengths more (0. 0001 to 0. 001 m) This creates the blue sky; the yellow sun is evidence of this removed blue sky: colorful sunsets. Low on the horizon, sun"s light passes through nearly 12 times more atmospheric gases and aerosols, enough to scatter shorter visible wavelengths strongly. Longer visible wavelengths like oranges and reds then comprise the sunlight, which reflects (scatters) from clouds and dust. The light is brighter closer to the light and has a blue hue to it.
