Frequency is the reciprocal of the period. The period is 5 seconds, so the frequency is 1/(5 s) = 0.20 Hz. 8. A common physics lab involves the study of the oscillations of a pendulum. If a pendulum makes 33 complete back-and-forth cycles of vibration in 11 seconds, then its period is ______.
Answers:The standard formula for the relationship between wavelength and frequency is: (wavelength) = c (speed of light) / v (frequency) (With this problem, you don't need Planck's constant (6.626 * 10^(-34)), that's only used when measuring energy a certain wavelength or frequency puts out.
