Period of a pendulum A standard pendulum of length L swinging under only the influence of gravity (no resistance) has a period of
where ω2 = g/L, k2 = sin2 (θ0/2), g ≈ 9.8 m/s2 is the acceleration due to gravity, and θ0 is the initial angle from which the pendulum is released (in radians). Use numerical

- 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.arrow_forwardHarmonic Motion The displacement from equilibrium of an oscillating weight suspended by a spring is given by y(t)=12cos6t where y is the displacement in feet and t is the time in seconds. Find the displacement when (a) t = 0, (b) t=14, and (c) t=12.arrow_forward
