No, time does not have a wavelength in the same sense that light or other electromagnetic waves do. Time is not a physical wave that propagates through space like light does. Instead, time is considered a dimension in which events occur and is often treated as a parameter in physics equations.
The quantum/classical boundary, also known as the quantum-classical divide or quantum-classical transition, refers to the observed differences between the behavior of particles at the quantum level and their behavior in classical physics. In the quantum realm, particles such as electrons and photons exhibit wave-particle duality, meaning they can behave as both particles and waves. This duality is described by quantum mechanics, which incorporates wave-like properties through mathematical equations known as wavefunctions.
The transition from quantum to classical behavior is not directly related to the size of particles or their access to time as a wavelength. Instead, it arises from the fundamental principles and mathematical formalism of quantum mechanics. In the macroscopic world, classical physics generally provides an accurate description of phenomena, while at the microscopic scale, quantum mechanics is needed to accurately predict and explain particle behavior.
The boundary between the quantum and classical realms is still an active area of research and remains a topic of debate among physicists. Various interpretations and theories attempt to explain why macroscopic objects do not exhibit quantum behavior on a large scale, but the definitive explanation is still an open question in physics.
