According to planck's theory radiation energy is neither emitted nor absorbed continuously

Radiation energy is neither emitted nor absorbed discontinuously

Explanation:
Planck's theory, also known as Planck's quantum theory, revolutionized our understanding of the behavior of energy at the atomic and subatomic level. It was proposed by the German physicist Max Planck in 1900.

Planck's theory is based on the idea that energy is quantized, meaning it can only exist in discrete packets or "quanta." This is in contrast to classical physics, which assumes that energy is continuous and can take any value.

The characteristic not associated with Planck's theory is that radiation energy is neither emitted nor absorbed discontinuously. This statement is incorrect because Planck's theory actually states that radiation energy is emitted and absorbed discontinuously, in discrete quanta or packets of energy.

Key points to understand about Planck's theory:

1. Radiations are associated with energy: Planck's theory recognizes that electromagnetic radiation, such as light, is associated with energy. This energy is carried by particles called photons.

2. The magnitude of energy associated with a quantum is proportional to frequency: Planck's theory introduces the concept of the quantum of energy, denoted as E. The magnitude of this energy is directly proportional to the frequency of the radiation, as given by the equation E = hf, where h is Planck's constant and f is the frequency.

3. Radiation energy is neither emitted nor absorbed continuously: Planck's theory postulates that energy is emitted or absorbed by matter in discrete amounts, or quanta. This means that energy is not transferred continuously, but rather in packets of specific energy values.

4. Radiation energy is emitted or absorbed discontinuously: According to Planck's theory, when an atom or a molecule undergoes a transition between energy levels, it emits or absorbs energy in discrete quanta. This explains phenomena such as the quantized emission spectra of elements and the photoelectric effect.

In conclusion, the characteristic not associated with Planck's theory is that radiation energy is neither emitted nor absorbed discontinuously. Planck's theory actually states that radiation energy is emitted and absorbed in discrete quanta, providing a fundamental understanding of the behavior of energy at the atomic and subatomic level.
