The dual nature of radiation was proposed by ………..

Options

A. Lowry
B. Heisenberg
C. de - Broglie
D. Schrodinger

Answer

To solve the question regarding who proposed the dual nature of radiation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**: The dual nature of radiation refers to the idea that light and other forms of electromagnetic radiation exhibit both wave-like and particle-like properties. This concept is fundamental in quantum mechanics.

2. **Identifying Key Figures**: The question asks for the individual who proposed this dual nature. The most notable figure associated with this concept is Louis de Broglie.

3. **De Broglie's Contribution**: Louis de Broglie proposed that if light can behave as both a particle (photon) and a wave, then matter (such as electrons) should also exhibit dual characteristics. This led to the development of wave-particle duality.

4. **Conclusion**: Based on the contributions of Louis de Broglie, we can conclude that he is the correct answer to the question.

5. **Final Answer**: The dual nature of radiation was proposed by Louis de Broglie.
