A monochromatic light beam (wavelength λ) is incident obliquely on the interface between two media with refractive indices n1 and n2, respectively. Snell-Descartes' law relates the refraction between the media with the angles of incidence and refraction. By finding the angle of refraction in an experiment, determine: (a) The speed of light in the second medium and (b) The refractive index of the second medium. Consider the speed of light in medium 1 equal to c and report the results in terms of n1, n2, angle of incidence, and refraction.

v = c * n1 / n2, n2 = n1 * sin(angle of incidence) / sin(angle of refraction)

v = c * n1 * n2, n2 = n1 * cos(angle of incidence) / cos(angle of refraction)

v = c * n1 / n2, n2 = n1 * cos(angle of incidence) / sin(angle of refraction)

v = c * n2 / n1, n2 = n1 * sin(angle of incidence) / cos(angle of refraction)

v = c * n2 / n1, n2 = n1 * cos(angle of incidence) / sin(angle of refraction)
