PROPOSTA SIMPLES PARA O EXPERIMENTO DE ESPALHAMENTO RAYLEIGH.

This work presents an alternative proposal for Rayleigh's scattering experiment presented and discussed in Krapas and Santos (2002) in this journal. Besides being simple and low-cost, the proposal suggested here is also proposing to demonstrate experimentally other physical phenomena such as polarization of light from the sky, the rainbow and reflection on non-conductive surfaces, as well as determine the direction of these biases. The polarization will be observed with the aid of Polaroid obtained from liquid crystal displays taken from damaged electronic devices and the Polaroid polarization direction will be established by the observation of Brewester's angle in reflection experiment.
