👉 Snell's law, named after James Clerk Maxwell, describes how light travels from one medium to another. This law states that the ratio of the angles of incidence and reflection (theta1/theta2) for a single incident ray in one medium is equal to the angle of refraction (n). Snell's law can be represented by the equation: \[ \frac{\sin\theta_1}{\sin\theta_2} = n \] This means that as light moves from
