This is because of the eddy curents produced due to the changing electric and magnetic fields.

High-frequency transformers could be transformers operating at frequencies higher than 50 or 60 Hz. An example is the transformers used in transport aircraft power supplies wh…ich operate at 400 Hz. This allows a transformer with a given power rating to made made with one eighth the mass of an equivalent transformer for a 50 Hz supply. Another type of high-frequency transformer is the tuned transformers used in radio systems. A tuned transformer passes signals over only a limited band of frequencies so is useful in radio receivers to tune out unwanted signals on different frequencies from the one that is needed. (MORE)

Yes. The frequency of the sound determines its pitch. The two are directly correlated. For example, the higher you go on a row of piano keys, the higher the frequency and the …higher the pitch. Yes. It is simply understood by the relation that frequency is directly proportional to pitch Yes. (MORE)

A wave with a high frequency has a low wavelength. Wavelength lambda and frequency f are connected by the speed c of the medium. c can be air = 343 m/s at 20 d…egrees celsius or water at 0 dgrees = 1450 m/s. c can be light waves or electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f (MORE)

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4

Pitch is directly proportional to frequency. So, yes, high pitch is equal to high frequency.
