Uncertainty Principle Hard

The Heisenberg Uncertainty Principle states that there is a fundamental limit to how precisely we can simultaneously know certain pairs of physical properties (conjugate variables). $Δ x \cdot Δ p \geq \frac{ℏ}{2}$ where $ℏ = \frac{h}{2 π}$ is the reduced Planck constant. This is not a limit of measurement tools, but a fundamental property of wave-like systems.

This hard difficulty physics question is from the chapter dual nature of radiation and matter, covering the topic of uncertainty principle hard. It appeared in the 2025 exam.
