E IPMEN Optics Kit containing Bench and Accessories Slit Mask St Plato INTRODUCTION Angle of Refraction The direction of light changes abruptly when it passes across a boundary between two different media of propagation, such as between air and plastic. The law of Refraction, also known as Snell's Law is: nl sin ql = n2 sin q2 The quantity nl is the index of refraction of the first material (in this case it is air) and sin anglel is the angle of incidence. N2 is the index of refraction of the second < Previous Dashboard Calendar Notifications Next Inbox
