Did you know that the relationship between frequency and periodic time is inversely proportional? This means that if the periodic time of body \( \mathrm{X} \) is double that of body \( \mathrm{Y} \), then the frequency of body \( \mathrm{X} \) will be half that of body \( \mathrm{Y} \). So, if we denote the frequency of \( \mathrm{Y} \) as \( f_Y \) and that of \( \mathrm{X} \) as \( f_X \), we can say \( f_Y = 2f_X \). When it comes to calculating frequencies, it’s crucial to keep an eye on the definitions. A common mistake is to interchange frequency and periodic time. Remember, frequency is the number of cycles per second (or Hertz, Hz), while periodic time is the duration of one complete cycle. So if you ever feel stuck, just flip your understanding – more time means less frequency, and vice versa!
