In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped. A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

We present a method for achieving sub-nanometer resolution images with amplitude-modulation (tapping mode) atomic force microscopy in liquid. The method is demonstrated on commercial atomic force microscopes. We explain the rationale behind our choices of parameters and suggest strategies for resolution optimization.

The technique presented here measures the path of freely swimming microscopic species using single wavelength exposure. C. elegans are used to demonstrate shadow imaging as an inexpensive alternative to costly microscopes. This technique can be adapted to accommodate various orientations, environments and species to measure direction, speed, acceleration and forces.
FAQs
When a wave enters a different medium, its propagation speed can change, but the source continues to set the frequency. The relationship v = fλ therefore requires wavelength to adjust with the new speed. This provides a practical way to interpret measurements at boundaries: a changed spacing between repeating features does not necessarily mean the source frequency changed.
Amplitude is useful for comparing the strength of oscillations because it indicates the magnitude of energy carried by the wave. Two waves may be examined using their spatial repetition and their displacement magnitude as separate measurements. This distinction helps prevent wavelength or frequency from being treated as a direct substitute for amplitude when interpreting wave behavior.
Amplitude and wavelength provide complementary information in phenomena such as interference, diffraction, and resonance. Wavelength helps identify the spatial scale of the repeating pattern, while amplitude indicates the oscillation's magnitude and associated energy-carrying strength. Considering both lets an analysis distinguish changes in spatial pattern from changes in wave strength when studying laboratory wave behavior.
Although mechanical, sound, electromagnetic, and matter waves differ in physical context, amplitude and wavelength remain useful quantities for characterizing them. Their interpretation is not identical in every application, but the same measurements support comparisons of oscillation magnitude and spatial repetition. This shared framework allows physics investigations to describe diverse wave systems with common quantitative properties.
To characterize a wave experimentally, researchers can measure the maximum displacement or strength indicator for amplitude and compare corresponding repeating features to determine wavelength. They can then combine wavelength with frequency in v = fλ when wave speed is relevant. Repeating these measurements across media reveals whether an observed change is associated with propagation speed, spatial spacing, or oscillation magnitude.
These measurements are especially valuable when the goal is to connect an observed wave pattern with a physical or engineered behavior. In laboratory studies, they support analysis of interference, diffraction, and resonance; in engineering contexts, they help assess signal behavior. The emphasis depends on whether the investigation concerns energy-carrying strength, spatial repetition, propagation, or a combination.
