6. A student learns that the
scattering of sunlight depends
on the wavelength of the light
and size of particles present in
the atmosphere. The student
collects the data about the
wavelength of the visible lights
and size of the particle as
shown. Which particles will
scatter blue light? *
Answers
Answer:
Atmospheric Scattering
Scatter
In addition to being absorbed or transmitted, electromagnetic radiation can also be reflected or scattered by particles in the atmosphere. Scattering is the redirection of electromagnetic energy by suspended particles in the atmosphere. The type and amount of scattering that occurs depends on the size of the particles and the wavelength of the energy. There are three main types of scattering that impact incoming solar radiation:
Rayleigh Scatter
Mie Scatter
Non-Selective Scatter
Rayleigh Scatter
Blue Sky
Rayleigh scatter occurs when radiation (light) interacts with molecules and particles in the atmosphere that are smaller in diameter than the wavelength of the incoming radiation. Shorter wavelengths are more readily scattered that longer wavelengths. Light at shorter wavelengths (like blue and violet visible light) are scattered by small particles that include NO2 and O2. Since blue light is at the short wavelength end of the visible spectrum, it is more strongly scattered in the atmosphere than longer wavelength red light. Rayleigh scatter is responsible for the blue color of the sky. Rayleigh scatter is can also produce haze in images. In aerial photography special filters are used to filter out the scattering of blue light to reduce haze. In digital images there are different techniques used to minimize the impacts of Rayleigh scatter.
At sunrise and sunset the incoming sunlight travels a longer distance (path length) through the atmosphere. The longer path leads to scatter of the short (blue) wavelengths that is so complete that we only see the longer wavelengths of light, the red and orange. In the absence of particles and scattering the sky would appear black
