Is the power in an electromagnetic wave equally transferred along both the electric and magnetic fields?
YesVanmathi Ravikumar said:Is the power in an electromagnetic wave equally transferred along both the electric and magnetic fields?
I now think (a) is not accurate because of the word "along", as it should say "by".Vanmathi Ravikumar said:option (b) does not specify what exactly are the fields. It just mentions it as both the fields. so i think that (a) is more accurate.
The wording suggests that power flows along the field lines, which is not correct.Vanmathi Ravikumar said:does'nt option (a) suggest that energy is equally divided between the electric and magnetic fields?
When there are viscous forces, work is done on regions of the medium and is not retrieved. In that case, there will be a net transverse work done during each half cycle.Vanmathi Ravikumar said:viscous forces
If you are dealing with EM, I have to ask you what transverse momentum? The momentum is in the longitudinal direction, surely.BvU said:I agree with Sophie (perhaps I never should have brought up the water analogy ). Nevertheless, momentum is transferred sideways.
Electromagnetic wave power transfer is a method of transferring energy wirelessly using electromagnetic waves. It involves the conversion of electrical energy into electromagnetic waves, which can then be transmitted through the air and converted back into electrical energy at the receiving end.
Electromagnetic wave power transfer works by using two devices - a transmitter and a receiver. The transmitter converts electrical energy into high-frequency electromagnetic waves and sends them out into the air. The receiver then captures these waves and converts them back into electrical energy to power a device or charge a battery.
There are several advantages to electromagnetic wave power transfer, including the ability to transmit energy wirelessly without the need for physical connections, high efficiency, and the ability to transfer energy over long distances. It is also a safe and environmentally friendly method of energy transfer.
One of the main limitations of electromagnetic wave power transfer is that it is affected by the distance between the transmitter and receiver. As the distance increases, the efficiency decreases, making it more difficult to transfer large amounts of energy. Additionally, it can be affected by obstacles and interference from other devices.
Electromagnetic wave power transfer has a wide range of potential applications, including wireless charging for electronic devices, powering remote sensors and devices, and even transferring energy to spacecraft in space. It could also be used for powering electric vehicles and providing electricity to remote areas without access to traditional power grids.
