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 full form of RF in space technology?
RF- Radio Frequency, which is in the measure of kilo & mega Hz range
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 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
If a note has a frequency of 400 hz how many sound waves per second?
If a note has a frequency of 400 Hz, it means that there are 400 sound waves produced in one second. The frequency of a sound wave is the number of complete waves that pass a point in one second.
What is the fourth harmonic of a fundamental frequency of 400 Hz?
1600HZ 400HZ x 4
What is the second octave of 200 Hz?
The second octave of 200 Hz is 400 Hz. In music theory, each octave represents a doubling of the frequency of the previous octave.
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 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.
How many wavelength is it 80Hz?
One wavelength for an 80 Hz wave is equal to the distance the wave travels during one period of oscillation, which is the reciprocal of the frequency. Therefore, for an 80 Hz wave, there is a distance equivalent to one wave in each 1/80th of a second.
What is the frequency of infrared per second?
Infrared radiation has a frequency range of about 3 x 10^11 Hz to 4 x 10^14 Hz. This means that the frequency of infrared light per second ranges from 300 GHz to 400 THz.
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.
What frequency does an airplane generator use?
An airplane generator typically operates at a frequency of 400 Hz. This high frequency is used to provide a more compact and lightweight design for the electrical system on aircraft.
Infra red frequency Hz?
Infrared light has a frequency range of about 300 GHz to 400 THz. The frequency of infrared radiation falls between microwaves and visible light in the electromagnetic spectrum.
If a note had a frequency of 400 Hz. State how many sound waves pass a point per second?
If a note has a frequency of 400 Hz, it means that 400 sound waves pass a point per second. This is because the frequency of a sound wave is the number of complete cycles of a wave that pass a point in a given time period, usually one second. Therefore, in this case, 400 complete cycles or sound waves pass a point in one second.
