Destructive electromagnetic waves

In summary, the conversation discusses the possibility of two photons that are 180 degrees out of phase passing through a surface and exerting tension on it. However, this is not possible as photons do not have a phase and quantum particles cannot be understood using classical notions. The wave functions of the photons would result in unlikely interactions with the surface.

Ive been wondering about this for about two days and i have a simple question and that is , if I have two photons that are 180 degrees out of phase, passing through a surface perpendicular to the photons velocity vector then will the EM fields exert tension on the surface?(in this case the material of the surface is not made up by any other constituent particles)

If they are exactly 180 degrees out of phase, there is no electromagnetic wave that could do anything.

This does not exist.

It doesn't work like that; we're dealing with quantum particles and you can't apply classical notions to them. A photon doesn't have "a phase" because it isn't like a little squiggle - as shown on the Feynman (peace be upon him), in his diagrams. The wave functions, associated with each of the sources of the two photons will combine to make it very unlikely that there will be a photon interaction with 'the screen' or detector at a minimum (calculated in a classical way) and very likely that there will be an interaction at a calculated maximum (or one of the maxima on either side of the central maximum).
 

FAQ: Destructive electromagnetic waves

What are destructive electromagnetic waves?

Destructive electromagnetic waves, also known as destructive interference, occur when two or more waves of the same frequency and amplitude combine and cancel each other out.

How do destructive electromagnetic waves affect our daily lives?

Destructive electromagnetic waves do not have a direct impact on our daily lives, as they are typically used in controlled environments such as laboratories for research purposes.

Can destructive electromagnetic waves cause harm to living beings?

No, destructive electromagnetic waves do not have enough energy to cause harm to living beings. They are typically used in low energy applications and do not have the ability to penetrate or damage cells.

What are some examples of destructive electromagnetic waves?

Examples of destructive electromagnetic waves include noise-cancelling headphones, where the sound waves produced by the headphones cancel out external noise, and anti-reflective coatings on glasses, where the coating cancels out reflections of light.

How are destructive electromagnetic waves different from other types of waves?

Destructive electromagnetic waves differ from other types of waves, such as constructive waves, by their ability to cancel out each other when they meet. This is due to their equal amplitude and frequency, causing them to destructively interfere with one another.
