The wave nature of the charged particle was proved by Davisson & Germer.

Here's a step-by-step explanation:

1. The wave nature of particles was first proposed by Louis de Broglie in 1924. He suggested that particles could exhibit properties of both particles and waves, a concept now known as wave-particle duality.

2. However, the experimental proof of this theory was provided by Clinton Davisson and Lester Germer in 1927.

3. Davisson and Germer conducted an experiment where they fired electrons at a nickel target. The pattern of scattered electrons created an interference pattern, which is a characteristic of waves.

4. This experiment confirmed de Broglie's hypothesis and proved that particles such as electrons do exhibit wave-like properties.

So, while de Broglie proposed the theory, it was Davisson and Germer who provided the experimental proof.
