The frequency of vibration of a lithotriptor, an ultrasound generator used to destroy kidney stones, is 1.23 MHz.

What is the period of vibration?

What is the angular frequency?

Answer :

Final answer:

The period of vibration for a lithotriptor with a frequency of 1.23 MHz is 8.13 x 10^-7 seconds, and its angular frequency is 7.72 x 10^6 rad/s.

Explanation:

The frequency of the lithotriptor is given as 1.23 MHz, which is 1.23 x 106 Hz. The period of vibration and the angular frequency can be calculated using the formulas:

  • Period (T) = 1/frequency (f)
  • Angular Frequency (ω) = 2π * frequency (f)

So, in order to find the period, we divide 1 by the frequency:T = 1/f = 1/(1.23 x 106) = 8.13 x 10-7 seconds.

To find the angular frequency, we multiply the frequency by 2π: ω = 2πf = 2π * (1.23 x 106) = 7.72 x 106 rad/s.
