Electromagnetic Waves: Metal Vibrations & Wave Generation

Click For Summary
Heating a metal causes its positive kernels to vibrate, which can indeed produce electromagnetic waves. This phenomenon is known as blackbody radiation, where the heated object emits energy in the form of electromagnetic waves. A common example of this is a standard light bulb, which generates light through the vibrations of its filament. The discussion highlights the relationship between temperature, vibration, and electromagnetic wave generation. Understanding this process is essential in fields like thermodynamics and optics.

When we heat a metal, the positive kernels begins to vibrate.Will this vibrations produce electromagnetic waves ?

Yes. This is called blackbody radiation.
 
Imagine a standard light bulb!
 

Thread 'What determines if wave components are independent vs coherent?'

I'm working through something and want to make sure I understand the physics. In a system with three wave components at 120° phase separation, the total energy calculation depends on how we treat them: If coherent (add amplitudes first, then square): E = (A₁ + A₂ + A₃)² = 0 If independent (square each, then add): E = A₁² + A₂² + A₃² = 3/2 = constant In three-phase electrical systems, we treat the phases as independent — total power is sum of individual powers. In light interference...
