The wave-particle duality of a photon, or any other quantum object, is not solely dependent on the detecting instrument being used. The wave-particle nature is an intrinsic property of quantum entities and is independent of the specific measuring device.
In quantum mechanics, the behavior of particles is described by wave functions, which can exhibit wave-like characteristics (such as interference and diffraction) and particle-like characteristics (such as discrete energy levels and momentum). This duality is not an artifact of the measurement process but is fundamental to the nature of quantum systems.
When a photon interacts with a detecting instrument, the measurement process reveals certain aspects of its wave-particle nature. The choice of the measuring device and the experimental setup can influence the type of information that is obtained, but they do not fundamentally change the nature of the photon itself.
Different experimental setups can emphasize different aspects of the photon's behavior. For example, using a double-slit experiment, photons can exhibit interference patterns, indicating their wave-like nature. On the other hand, in certain measurements such as photon counting, the discrete nature of photons as particles is more apparent.
It's important to note that the wave-particle duality is a fundamental property of quantum objects and is not solely a result of the measurement process or the choice of the detecting instrument. The behavior of quantum systems is inherently probabilistic and can display wave-like or particle-like characteristics depending on the experimental context.
