Pesquisa e conceituação de um espectrômetro óptico
(2021-04-07)
According to Ferreira (2012) the spectral response of a photovoltaic device is its ability
to convert the incident radiation from certain bands of the spectrum in electrical energy.
Therefore, when analyzing the spectral ...

(2021-02-09)
This work has as main objective to present the construction of a low-cost gravimeter, which can measure the value of gravitational acceleration. The equipment uses a Michelson-Morley interferometer where one of its mirrors ...
Dos atomistas ao átomo moderno: um resgate histórico da evolução dos modelos atômicos
(2021-02-25)
The present work presents a survey of the evolution of atomic models, starting from the
Greek thought with the first ideas of the atomists, passing through the atomic models of
the classical era and culminating in the ...
Construção de um aparato experimental de baixo custo para análise espectral e inserção do modelo atômico de Bohr no ensino de física moderna
(2021-02-08)
In the developed paper, we built a low cost spectrometer for measuring the
wavelengths of the spectral lines of gas lamp radiation, which can be used in teaching
the Bohr atomic model. The preparation of the project was ...
