I have a few questions.
I know that EM waves transfer energy. So when they are generated why do they form curves? Are energy packets moving in a curvy path, or energy packets (quanta) not considered when wave is propagating? OR are the electric and magnetic FIELDS curvy in nature? NUTSHELL: Why is the EM wave curly and how do we know that they are curvy?
When ever we heat an object, the energy supplied makes the electrons oscillate due to which they radiate electromagnetic waves of which frequency rises as temperature rises. At certain temp. First, the red colour comes and then as we heat further blue comes because frequency is rising, my interpretation says that if we heat it further the object would radiate waves with frequency higher than the visible range and we couldn't be able to see the object glow. Am I right? The main thing is that books write that waves are formed because electrons oscillate and they want to become stable but atoms are also moving when heated and so the positive nucleus is also oscillating due to which EM waves should be produced because whenever charged objects accelerate they radiate energy. First of all, is this true? Second of all, why do they radiate energy? Is to become stable or something like that?
I attended a lecture which said that every object is radiating energy But I don't understand why? Is this because of environment? Or is it because electrons are oscillating and radiating energy or something like that?
The famous question that electron have uniform centripetal acceleration so they would radiate energy and spiral in to the nucleus! Why can't a body moving at a uniform velocity in an Electromagnetic field radiate off its energy? What is so special about accelerated Motion?
The Bohr model was proposed to solve this major problem, by postulating that the energy is quantised.
I don't understand this, So what if energy is quantised? How does this means that energy cant be radiated (or absorbed?)?
