OSCILLATIONS AND WAVES: The Period of a Pendulum

Q: A pendulum has a length of 2.45 m. How many seconds will it take the pendulum to swing through one complete cycle? Does the mass of the pendulum influence the period? Why or why not? A: This question regards the period ( T ) of a pendulum. The period ( T ) is definedContinue reading “OSCILLATIONS AND WAVES: The Period of a Pendulum”

RADIANT ENERGY: Wavenumber, Angular Frequency, and the Wave Nature of Light

Trigonometric functions such as sin ( θ ) and cos ( θ ) are commonly used to model the oscillating motion of traveling waves. In the diagram above, a complete wave cycle occurs from crest-to-crest, trough-to-trough, or along the x-axis as indicated by the blue line. Since the diagram above can be modeled with theContinue reading “RADIANT ENERGY: Wavenumber, Angular Frequency, and the Wave Nature of Light”
