Kit for the study of light scattering OPTIKA SCIENCE.

why is the sky blue at noon, and at dawn and dusk it turns red? When the size of the particles affected by optical radiation is comparable to the wavelength of the incident light, light scattering occurs. The blue component of solar radiation has a wavelength comparable to the particle size of the gases present in the atmosphere and therefore diffuses to a greater extent than the other components. For this reason, our eye sees a clear blue sky. On the contrary, at sunset, the light passes through a layer of the upper atmosphere that gathers many solid particles (dust) which spreads to a greater extent to the red component.

With this equipment, the phenomenon of forward scattering can be observed on a screen. With a polarization filter it is also possible to check the partial polarization state of the scattered light.

The projector must be purchased separately.
