Further,
according to the classical electromagnetic theory, the
frequency of the electromagnetic waves emitted by the
revolving electrons is equal to the frequency of
revolution As the electrons spiral inwards, their angular
velocities and hence their frequencies would change
continuously, and so will the frequency of the light
emitted Thus, they would emit a continuous spectrum,
in contradiction to the line spectrum actually observed Clearly Rutherford model tells only a part of the story
implying that the classical ideas are not sufficient to
explain the atomic structure
