at what conditions will light, and an electron behave as a wave and as a particle?

The wave-particle duality is a fundamental concept in quantum mechanics that describes the behavior of light and electrons. It states that these particles can exhibit both wave-like and particle-like properties, depending on the experimental setup.
The double-slit experiment, first performed by Thomas Young in 1801, demonstrated that light can behave as both a wave and a particle. This was further confirmed by the famous experiment conducted by Davisson and Germer in 1927, which showed that electrons can also exhibit wave-like behavior.
The wave-like properties of light include interference, diffraction, and polarization. These phenomena can only be explained by considering light as a wave. Similarly, the diffraction of electrons and their ability to interfere with each other also demonstrate their wave-like nature.
The wave-particle duality challenges our classical understanding of physics and introduces the concept of duality, where a particle can exist as both a wave and a particle simultaneously. It also plays a crucial role in modern technologies such as quantum computing and particle accelerators.
No, according to the Heisenberg uncertainty principle, it is impossible to simultaneously measure the position and momentum of a particle. Therefore, we can only observe the wave-like or particle-like behavior of light and electrons, but not both at the same time.
