Davisson - Germer experiment establishes the .............nature of slow moving electrons.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Context**: The Davisson-Germer experiment is a significant experiment in physics that demonstrates the dual nature of electrons. It is important to recognize that electrons exhibit both particle and wave properties.

2. **Identifying Known Properties**: Initially, electrons were known to have particle nature. This was established when electrons were discovered and identified as particles with mass.

3. **Exploring Wave Nature**: The Davisson-Germer experiment provided evidence that electrons also exhibit wave properties. This was shown through the scattering of electrons and the formation of an interference pattern.
