# Activity of photon during wavelegnth duration

• acesuv
In summary: If the radiation has a range of frequencies, then the average number of photons at each frequency is N = E / (2πf).

so like... a radio wave has a rather macroscopic wavelength. the photon is depicted as traveling back and forth in unison with the wavelength. I am having trouble understanding why the photon can't hit you from the "side". if the photon is traveling a zig-zaged path (zig zags due to wavelength), then is it possible for the photon to actually hit you from the "side"? if you get hit by a radiowave when its coming back down from its wavelength, it has some velocity in a direction which the light isn't actually travelling. I am thinking uncertainty principals somehow negate this? please help thanks

No, it doesn't do that. Where have you seen this depicted?

im not sure. i did a google image search and couldn't find any depictions of such, which discourages me.

thanks

The sinusoidal "pictures" that you usually see of electromagnetic waves are supposed to represent the behavior of classical electric and magnetic fields. They show the magnitude and direction of those fields at various points, at various times, not the motion of actual objects.

The relationship between classical electric and magnetic fields on one hand, and quantum-electrodynamical photons on the other hand, is rather complex and subtle. Unless you know QED well, it's dangerous to try to connect the two.

The safest way is via energy: classical electric and magnetic fields carry energy. A volume of space "filled" with electromagnetic radiation contains a certain amount of energy E, which we can calculate from classical electrodynamics in terms of the amplitudes of the electric and magnetic fields. Looking at this in terms of photons, each photon has energy hf. So if the radiation has a single frequency, then we can say the average number of photons in that volume is N = E / hf.

## 1. What is the relationship between the activity of a photon and its wavelength duration?

The activity of a photon refers to its ability to interact with matter, while its wavelength duration is a measure of the distance between two consecutive peaks or troughs in the photon's wave pattern. The energy of a photon is directly proportional to its frequency, which is inversely proportional to its wavelength. Therefore, the activity of a photon increases as its wavelength decreases.

## 2. How does the activity of a photon change during its wavelength duration?

The activity of a photon remains constant during its wavelength duration. As the photon travels, it maintains its frequency and energy, resulting in a consistent level of interaction with matter. However, the number of photons present in a specific wavelength duration may vary depending on the intensity of the light source.

## 3. Can the activity of a photon be measured during its wavelength duration?

Yes, the activity of a photon can be measured using various techniques such as spectroscopy or photometry. These methods involve detecting the interactions of photons with matter and measuring their intensity, which can then be correlated to the activity of the photon.

## 4. How does the activity of a photon relate to the color of light?

The color of light is determined by its wavelength, which is directly related to the activity of a photon. Shorter wavelengths correspond to higher energy photons, which are perceived as blue or violet light. Longer wavelengths correspond to lower energy photons, which are perceived as red or orange light.

## 5. Does the activity of a photon change when passing through different mediums?

Yes, the activity of a photon can change when passing through different mediums. This is because the speed of light and therefore the wavelength of the photon can be affected by the medium it is traveling through. This phenomenon is known as refraction and can result in changes in the activity of the photon.
