Show that you can use Snell’s Law ( n1sinΘ1 = n2sinΘ2) to predict the angle of reflection and angle of refraction for several scenarios. Show your work. After you have completed the calculations, use simulation to check your work For incident angle of 30 degrees light shining a. from air into water b. from water into air c. from air into glass d. from water into glass e. from air into a medium with an index of 1.22

Most short-period comets do not have randomly oriented orbits because
