It most definitely works to keep female mosquitoes away. Females are the ones that "bite" us and leave itchy, red welts on our skin.
they are used in industries so to able you to work on particular frequency and cut the other for e.g if you are working for high frequency then low frequency will be cut and vise versa
They don't although some have had some short term results. it uses high frequency sound to irritate & repel but of course, they get used to it & not all pests will find it unpleasant. Don't waste your money as every pest co has tried them & no one uses them. If they worked, they all would.
the op amp is a one IC which does not work at hige volteg so the IC not consumed the high frequncy
Yes, you can have a high bass frequency. Prolonged exposure to high frequencies can cause hearing loss. In audio work, "bass" usually refers to the low frequencies; "treble" refers to higher frequencies.
Diodes have capacitance, placing a limit on their switching rate.
It goes from longer waves, to shorter waves. Another words Low Frequency to High frequency. I'm not quite sure how to explain how they EACH as and individual wave work.
A high frequency induction motor uses high frequency electrical currents to create a rotating magnetic field in the stator. This rotating field induces currents in the rotor, which causes it to rotate and drive the motor. The higher frequency allows for more precise speed control and efficiency in certain applications.
They use high frequency sound we humans can't hear, but don't really work.
because the vibration is so fast your ears hurt low pitched sounds vibrate slowly and doesn't hurt
High treason.
Allele frequency is stable
Noise cancellation headphones work by blocking high-frequency sound waves and erasing lower-frequency sound waves. This can occur due to their ability to mimic incoming noise in order to produce their own sound waves.
