The correct Answer is:
To solve the question regarding Planck's Quantum Theory, we will analyze each statement one by one to determine its correctness. ### Step-by-step Solution: 1. **Statement A: The vibrating particle in the black body does not emit continuously.** - According to Planck's Quantum Theory, particles (like electrons) in a black body do not emit energy continuously. Instead, they emit energy in discrete amounts or packets. Therefore, this statement is **correct**. 2. **Statement B: Radiation is emitted in the form of small packets called Quanta.** - Planck proposed that energy is emitted in discrete packets called "quanta". This is a fundamental concept of quantum theory. Hence, this statement is also **correct**. 3. **Statement C: Energy associated with emitted radiations is inversely proportional to frequency.** - The relationship between energy (E) and frequency (ν) is given by the equation \( E = hν \), where \( h \) is Planck's constant. This shows that energy is directly proportional to frequency, not inversely. Therefore, this statement is **incorrect**. 4. **Statement D: The emitted radiant energy is propagated in the form of waves.** - While energy is emitted in quanta, it is also true that electromagnetic radiation (like light) propagates as waves. This means that the statement is **correct**. ### Conclusion: The correct statements according to Planck's Quantum Theory are **A, B, and D**. ### Final Answer: The correct statements are: **A, B, D**. ---
