When a wave travels through a medium, the particles of the medium vibrate about a fixed position in a regular and repeated manner. The period describes the time it takes for a particle to complete one cycle of vibration. The frequency describes how often particles vibration - i.e., the number of complete vibrations per second. These two quantities - frequency and period - are mathematical ...
26 de abr. de 2024 · Write your answer in Hertz, or Hz, which is the unit for frequency. If you need to calculate the frequency from the time it takes to complete a wave cycle, or T, the frequency will be the inverse of the time, or 1 divided by T. Display this answer in Hertz as well. Keep reading to learn how to calculate frequency from angular frequency!
