# Uniformly accelerating charge and radiation

• Selfluminous
In summary, when a charge accelerates, it produces changing electric and magnetic fields, resulting in the emission of electromagnetic radiation. The amount and frequency of radiation emitted is directly proportional to the square of the acceleration, meaning that as acceleration increases, so does the intensity and frequency of the emitted radiation. Unlike a stationary charge, a uniformly accelerating charge emits radiation that can be harmful if absorbed by living cells. It is important to limit exposure to sources of radiation in order to avoid potential harm.

Last night when i was bored, i googled some stuffs about radiation of accelerating charge and saw this http://www.mathpages.com/home/kmath528/kmath528.htm

I don't understand the beginning of the article, what does the author mean by "stationary and accelerating" ? or "stationary" ?

## 1. How does a uniformly accelerating charge produce radiation?

When a charge accelerates, it creates a changing electric field. This changing electric field produces a magnetic field, and the interaction between the two fields results in the emission of electromagnetic radiation.

## 2. What is the relationship between the rate of acceleration and the amount of radiation emitted?

The amount of radiation emitted by a uniformly accelerating charge is directly proportional to the square of the acceleration. This means that as the acceleration increases, the amount of radiation emitted also increases exponentially.

## 3. Does the frequency of radiation emitted by a uniformly accelerating charge change?

Yes, the frequency of the radiation emitted by a uniformly accelerating charge is directly proportional to the acceleration. As the acceleration increases, so does the frequency of the emitted radiation.

## 4. How does the radiation emitted by a uniformly accelerating charge differ from that of a stationary charge?

A stationary charge does not emit radiation, while a uniformly accelerating charge does. The radiation emitted by a uniformly accelerating charge is also more intense and has a higher frequency compared to that of a stationary charge.

## 5. Can the radiation emitted by a uniformly accelerating charge be harmful?

Yes, the radiation emitted by a uniformly accelerating charge can be harmful if the charge is accelerating at a high enough rate and if the radiation is absorbed by living cells. This is why it is important to limit exposure to sources of radiation, such as X-rays and gamma rays.
