Measurement of Faraday Rotation in SF57 glass at 670 nm Third and Final Draft

Abstract

We performed an experiment to measure the Faraday rotation of polarized light passing through a magnetic field, as well as measuring the Verdet constant of an SF57 glass tube with a length of \(0.1\) m. Our results are consistent with the general idea of Faraday rotation, which suggests that linearly polarized light experiences rotation when applying a magnetic field. We used three different methods to find Verdet constants, which are Direct Fit, Slope Fit and Lock-in Method. The values we found are \(21\pm 5 \frac{radians}{T \cdot m}\), \(21.095\pm0.003 \frac{radians}{T \cdot m}\) and
