Total Internal Reflection When light passes from a more dense to a less dense medium-from glass to air, for example-the angle of refraction predicted by Snells Law see exercise 57 can be 90 or large. In this case the light beam is actually reflected Bach into the denser medium. This phenomenon, called total internal reflection, is the principal behind optics. Set 2=90 in Snells Law, and solve for 1 to determine the critical angle of incidence at which total internal reflection begins to occur when light passes from glass to air. Note that the index of refraction from glass to air is reciprocal of the index from air to glass.

The displacement from equilibrium of an oscillating weight suspended by a spring is given by y(t)=3sin(t/4), where y is the displacement in feet and t is the time in seconds. Complete the table Use the table feature of a graphing utility to determine when the displacement is maximum. Use the table feature of the graphing utility to approximate the time t (0 < t < 8) when the weight reaches equilibrium.
Simple Harmonic Motion A mass suspended from a spring oscillates in simple harmonic motion at a frequency of 4 cycles per second. The distance from the highest to the lowest point of the oscillation is 100 cm. Find an equation that describes the distance of the mass from its rest position as a function of time. Assume that the mass is at its lowest point when t=0.
