Does it increase, decrease, double or stay the same.
Yes. If the male has already inserted himself into you and has not ejaculated then penetration has occurred.
what is resonant frequency
Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
That's normal. You'll probably see it later in the pregnancy if the ultrasound is repeated.

Frequency Increases
As wavelength increases the frequency decreases.
the frequency reduces in value. The longer the wavelength the lower the frequency.
if the machine is broken than nothing happens
I assume you mean the frequency at which the head moves back and forth. If this happens only at a certain frequency, then it sounds as if that is caused by resonance - which happens when the excitation (in this case, the head moving back and forth) has a similar frequency to the object's (the printer's) natural frequency.
Frequency is how often something happens.
Its frequency increases.
