Why does the classical electromagnetic theory predict a continuous spectrum, in contradiction to the line spectrum actually observed?
Why does the classical electromagnetic theory predict a continuous spectrum, in contradiction to the line spectrum actually observed?
- Because the frequency of the electromagnetic waves emitted by revolving electrons is equal to their frequency of revolution.
- Because the angular velocities of electrons continuously change as they spiral inwards.
- Because the classical ideas are not sufficient to explain atomic structure.
- Because the frequency of the light emitted changes continuously as the electrons spiral inwards. (correct)
What does the classical electromagnetic theory imply about the relationship between the frequency of electromagnetic waves and the revolution of electrons?
What does the classical electromagnetic theory imply about the relationship between the frequency of electromagnetic waves and the revolution of electrons?
- Their relationship fluctuates.
- They are inversely proportional.
- They have no relationship.
- They are equal. (correct)
Why does the Rutherford model only tell a part of the story regarding atomic structure?
Why does the Rutherford model only tell a part of the story regarding atomic structure?
- Because it doesn't address the behavior of electrons in atomic orbits.
- Because it fails to explain why electrons spiral inwards.
- Because classical ideas alone are insufficient to explain atomic structure. (correct)
- Because it doesn't consider the wave nature of electrons.
