Identify each symbol in the formula: \( n_{1} \sin \theta_{1}=n_{2} \sin \theta_{2} \)

The formula \( n_{1} \sin \theta_{1} = n_{2} \sin \theta_{2} \) is known as Snell's Law, which describes the relationship between the angles of incidence and refraction when light passes between two different media. Here’s what each symbol represents: - \( n_{1} \): The refractive index of the first medium (where the light is coming from). - \( n_{2} \): The refractive index of the second medium (where the light is entering). - \( \theta_{1} \): The angle of incidence, which is the angle between the incident light ray and the normal (a line perpendicular to the surface) at the interface of the two media. - \( \theta_{2} \): The angle of refraction, which is the angle between the refracted light ray and the normal in the second medium. In summary, this equation relates the angles of incidence and refraction to the refractive indices of the two media involved.
