Planks theory says energy is emitted__________________?
Correct answer: B. Discontinuous manner
- A. In continuous manner
- B. Discontinuous manner
- C. Simultaneously
- D. In the form of heat
Explanation
Planck proposed that energy is emitted or absorbed in definite packets called quanta, so the exchange is discontinuous rather than continuous. Students may choose a because classical physics treated radiation as a continuous flow of energy.

About Planck's Quantum Theory
Planck's quantum theory states that energy is emitted or absorbed in discrete packets called quanta, with each packet having energy E = hν. It covers the meaning of Planck's constant, the relationship between frequency and wavelength, and how quantisation differs from the classical continuous model of energy.
