The uncertainty principle and the concept of wave nature of matter were proposed by ______ and ________ respectively.

Explanation

To fill in the blanks in the statement "The uncertainty principle and the concept of wave nature of matter were proposed by ______ and ________ respectively," we need to identify the correct scientists associated with these concepts.

1. **Identify the first concept: Uncertainty Principle**
- The uncertainty principle is a fundamental theory in quantum mechanics that states that certain pairs of physical properties, like position and momentum, cannot be simultaneously known to arbitrary precision. This principle was formulated by **Werner Heisenberg**.

2. **Identify the second concept: Wave Nature of Matter**
- The concept of wave nature of matter, which describes how particles can exhibit wave-like behavior, was proposed by **Louis de Broglie**. He introduced the idea that all matter has wave properties, leading to the development of wave mechanics.
