SUMMARY
Light traveling through different mediums, such as water and air, is governed by Snell's Law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the speeds of light in the respective mediums. Specifically, the equation is expressed as \(\frac{\sin \theta_1}{\sin \theta_2} = \frac{c_1}{c_2} = \frac{n_2}{n_1}\), where \(n_i\) represents the refractive index calculated as \(c / c_i\). This law is critical for understanding how light bends when transitioning between mediums with different refractive indices.
