Why do atoms emit discrete frequencies of light?

AI Thread Summary
Atoms emit discrete frequencies of light due to their quantized electronic energy levels, which dictate the specific positions of electrons. These energy levels arise from quantum mechanics, particularly illustrated by Niels Bohr's model of the hydrogen atom, which, despite being outdated, effectively introduces the concept of energy quantization. Different atoms possess unique sets of energy levels, leading to the emission of distinct light frequencies when electrons transition between these levels. Understanding these principles is essential for grasping atomic behavior and spectral lines. The study of these discrete energy states is fundamental in fields such as spectroscopy and quantum physics.

Why are electronic levels present for an atom? What is the need for differentiating energy levels?

What do you think?
 
I was taught that energy levels are used for differentiating the position of an electron in an atom. Why is that it needs to be specific levels?
 
I guess you are asking why different atoms have different discrete energy states and if so the best answer comes from quantum theory.It will help if you study Niels Bohr's analysis of the hydrogen atom.Try googling "Bohr atom".The analysis can be described as being obsolete but it is still widely studied because it introduces the concept of energy levels and it makes a good introduction to the subject.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
