Higher the fequency , higher the speed. Similarly,freq is inversely proportional to the the flux , higher the freq lower the flux requirement hence lower the winding req. which will reduce the weight ( this is necessary req. in operation of Aeroplane) of the winding
The higher frequency allows a lighter transformer. Doubling the frequency allows the transformer's iron core to be half the weight. So 400 Hz allows light Transformers (and motors) to be used.

What is the difference between frequency and pitch?
The human ear is capable of detecting sound at frequencies between about 20 and 20,000 Hz. Within this frequency range, however, the response of the ear is not uniform. The ear is most sensitive to frequencies between 200 and 4000 Hz, and its response decreases toward both higher and lower frequencies. There are wide variations in the frequency response of individuals. Some people cannot hear sounds above 8000 Hz, whereas a few people can hear sounds above 20,000 Hz. Furthermore, the hearing of most people deteriorates with age. The sensation of pitch is related to the frequency of the sound. The pitch increases with frequency. Thus, the frequency of middle C is 256 Hz, and the frequency of the A above is 440 Hz. There is, however, no simple mathematical relationship between pitch and frequency. frequency causes the different types of pitch
What is the industrial frequency?
Industrial frequency, as used in Communications, aka the ISM band, is the frequency of signals between 900Mhz to around 2.4Ghz of encoded, compressed, or analog signals... industrial frequency can also refer to the common local power grid frequency (usually 60 or 50 Hz)
What is the full form of RF in space technology?
RF- Radio Frequency, which is in the measure of kilo & mega Hz range
What is the bandwidth of a signal composed of frequencies from 50 Hz to 500 Hz?
The bandwidth of a signal is the width of frequencies between the highest and the lowest frequency. So 500Hz - 50Hz = 450Hz bandwidth. AE7HD
Why does your Sharp microwave make a low humming noise when it is not in use?
A microwave oven is always switched on, even when it isn't cooking anything. It needs to be in order to recognize your commands and to have a clock. This means that there is a power transformer, and if the transformer laminations are slightly loose, they will vibrate in response to the 60 Hz magnetic field. That means that you will hear a 60 Hz or 120 Hz hum. If your power supply is some other frequency, like 50 Hz, you will hear a 50 Hz or 199 Hz hum. An expensive encapsulated transformer would fix this.
What is the frequency of ultra violet?
400 HZ
Infra red frequency Hz?
10 Tera hertz to 400 Tera hertz.
What is the fourth harmonic of a fundamental frequency of 400 Hz?
1600HZ 400HZ x 4
How many wavelength is it 80Hz?
400 Hz means 400 cycles per second, so each wave passes a point 400 times in one second
What is the frequency of a note one octave higher than 200Hz?
200
If a bulb has 50 Hz frequency and it is apply at 60 Hz frequency voltage supply then it is glow or not?
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.
Why 400 HZ for air crafts?
400 Hz is used in aircraft because it allows transformers to be much smaller than if the frequency was lower. A 50 Hz transformer would weight eight times as much. But 400 Hz is not useful for transmitting over distances of more than a few hundred metres because of power losses.
If a note had a frequency of 400 Hz. State how many sound waves pass a point per second?
What is the frequency of ultra-violet?
The wavelength of ultraviolet light is between 10 and 400 nanometers (nm).From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency.The frequency range would be from 7.5 x 1014 Hz to 3 x 1016 Hz.
Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
When a sound wave with a frequency of 256 Hz overlaps with a sound wave with a frequency of 250 Hz what would the frequency of the beats be?
There should be two beat frequencies produced: 506 Hz and 6 Hz.
Two notes are sounding one of which is 370 Hz If a beat frequency of 5 Hz is heard what is the other note's frequency?
365 Hz or 375 Hz.
