In short: the uncertainty principle describes a trade-off between two complementary properties, such as speed and position. The uncertainty principle for energy and time and position and momentum. Conversely, if we wanted to know the exact position of one peak of a wave, we would have to monitor just one small section of the wave and would lose information about its speed. The number of photons per unit time in the incident light is proportional to the. We measure its position using metre sticks and we get a measurement of x 2.34 x 2.34 m. For example, we do an experiment to measure the position of a box with respect to an origin. The location is spread out among the peaks and troughs. 1 Answer Sorted by: 2 Uncertainties are written with the same units as to what is being measured. However, this possibility is absent in the quantum world. The more peaks and troughs that pass by, the more accurately we would know the speed of a wave-but the less we would be able to say about its position. Uncertainty Principle Last updated Quantum Theory Wave-Particle Duality In classical physics, studying the behavior of a physical system is often a simple task due to the fact that several physical qualities can be measured simultaneously. To measure its speed, we would monitor the passage of multiple peaks and troughs. To understand the general idea behind the uncertainty principle, think of a ripple in a pond. Quantum objects are special because they all exhibit wave-like properties by the very nature of quantum theory. Though the Heisenberg uncertainty principle is famously known in quantum physics, a similar uncertainty principle also applies to problems in pure math and classical physics-basically, any object with wave-like properties will be affected by this principle. In other words, if we could shrink a tortoise down to the size of an electron, we would only be able to precisely calculate its speed or its location, not both at the same time. Formulated by the German physicist and Nobel laureate Werner Heisenberg in 1927, the uncertainty principle states that we cannot know both the position and speed of a particle, such as a photon or electron, with perfect accuracy the more we nail down the particle's position, the less we know about its speed and vice versa.
