mega = 1,000,000
1MHz = 1,000,000 Hz.
21.58 Megahertz.
If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
Hz = hertz ,which is a measure of frequency. It is equivalent to cycles per second. Your home power is 60 Hz if you live in USA.
It is a motor where the frequency of the AC voltage is 50 cycles per second. In U.S.A. 60 Hz is standard. 50 Hz would be overseas.
loudbetween 1,000 Hz and 5,000 Hz ... centered at 3500 Hz - a very sensitive frequency range for the human ear .. go figure
150 kHz = 150 000 Hz and 29 MHz = 20 000 000 Hz
1 GHz is equal to 1,000,000,000 Hz.
0.523 kHz is equal to 523 Hz. Just multiply the value in kHz by 1000 to convert it to Hz.
There are 0.001 kHz in 1 Hz. This is because 1 kilohertz (kHz) is equal to 1000 hertz (Hz).
21.58 Megahertz.
10 Hz 10 Hz
The 'k' in kHz probably stands for kilo, meaning a thousand times Hz, like kilogram and gram.
The first harmonic of 220 Hz is 220 Hz, the second harmonic is 440 Hz, and the third harmonic is 660 Hz. These harmonics are multiples of the fundamental frequency (220 Hz) that create different pitches when combined.
The k stands for thousand, so 1kHz is 1 000Hz
1000 Hz. The others are outside the range of human hearing. You can feel 10 Hz but not hear it. C. 1,000 Hz
When the C in the middle is 256 Hz, the corresponding frequencies on either side are approximately 227.18 Hz for B and 271.63 Hz for D. This is based on the equal-tempered scale used in Western music.
There is no inherent disadvantage of 50 Hz compared with 60 Hz, bearing in mind that systems that run at 50 Hz are designed to run at 50 Hz.
