# What is the equation for working out emf frequency

Hi there
My understanding is that any charge will produce some emf when it is accelerated..is this always true? What is this law called? Is there a simple equation to relate charge size, acceleration rate and resulting emf frequency?

Many thanks

yes

from wiki ...

Maxwell's equations describe how electric and magnetic fields are generated and altered by each other and by charges and currents.

https://en.wikipedia.org/wiki/Maxwell's_equations

have a read of that and other related articles

coming to understanding that will take the next few years
I don't even begin to understand it all

Dave

EDIT
PS ... I just noticed you used the term emf frequency ... am assuming you really meant
E/M electromagnetic field

Thanks..sorry I meant emr (electromagnetic radiation) frequency

## 1. What is EMF frequency?

EMF frequency, also known as electromagnetic frequency, is a measurement of the rate at which electromagnetic waves oscillate. It is expressed in units of hertz (Hz) and represents the number of complete waves that pass a given point in one second.

## 2. What is the equation for calculating EMF frequency?

The equation for calculating EMF frequency is f = E/h, where f is the frequency in hertz, E is the energy of the electromagnetic wave in joules, and h is Planck's constant in joule-seconds.

## 3. How is EMF frequency related to wavelength?

EMF frequency and wavelength are inversely proportional. This means that as the frequency increases, the wavelength decreases, and vice versa. The relationship is described by the equation f = c/λ, where c is the speed of light in meters per second and λ is the wavelength in meters.

## 4. What is the relationship between EMF frequency and energy?

The energy of an electromagnetic wave is directly proportional to its frequency. This means that as the frequency increases, the energy also increases. The relationship is described by the equation E = hf, where E is the energy in joules, h is Planck's constant, and f is the frequency in hertz.

## 5. How is EMF frequency measured?

EMF frequency can be measured using specialized instruments such as an oscilloscope or a frequency counter. These instruments detect the frequency of electromagnetic waves and display it in hertz. EMF frequency can also be calculated using the equations mentioned above if the energy or wavelength is known.
