Since light is a type of EM wave, wouldn't that mean that when you flash a beam of light on a system of charges, you're exerting electric and magnetic fields onto the system?
Gear300 said:Wouldn't that mean that a current is generated in those devices (which, because of the oscillations, would be an alternating current)?
Also...wouldn't this make photons electromagnetic packets of energy?
Gear300 said:Interesting stuff...since it was mentioned that the vacuum state has energy, has there also been consideration of space-time energy (assuming space-time and the vacuum have some commonality)?
Gear300 said:Interesting...I know less than or about as much as the amateur when it comes to modern physics...I was (or still am) unaware of the essence of QFT (all I really knew was that it existed and it was related to quantum mechanics) and was unaware of this theory of the matter field (though, ironically, I was aware of the theoretical existence of the Higgs Boson...which is stuff that one can pick up in readings on physics for the layman). Is the Higgs Boson the energy quantum of the matter field?
Light is a type of electromagnetic (EM) wave, which means it is made up of oscillating electric and magnetic fields that travel through space. This means that light exhibits all the properties of electromagnetic waves, such as wavelength, frequency, and speed.
When light interacts with charged particles, such as electrons, it can cause them to move and accelerate. This is because the electric and magnetic fields in light exert forces on charged particles. This effect is the basis for many technologies, including solar panels and the operation of electronic devices.
No, light cannot create or destroy charges. Charges are fundamental properties of matter and cannot be created or destroyed. However, light can cause charges to move and redistribute, creating electric currents and other effects.
The intensity of light refers to the amount of energy carried by the electromagnetic wave. Higher intensity light can cause greater movement and acceleration of charges. This is why brighter light can create stronger electric currents and have more powerful effects on charged particles.
Light has the potential to damage or disrupt electronic devices, as it can cause unexpected movements of charged particles. In large enough doses, light can also cause burns and other harmful effects on living organisms. However, these risks can be mitigated through proper precautions and understanding of light's properties.
