Manipulating fluids and suspended particles in the micro- and nano-scale is becoming more of a reality as enabling technologies, like AC electrokinetics, continue to develop. Here, we discuss the physics behind AC electrokinetics, how to fabricate these devices and how to interpret the experimental observations.

Standing Waves

Source: Arianna Brown, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA Standing waves, or stationary waves, are waves that appear not to propagate and are produced by the interference of two waves traveling in opposite directions with the same frequency and amplitude. These waves appear to vibrate up and down with no linear movement and are most easily identified in vibrating finite media like a plucked guitar string,...

Drug Abuse and Addiction: Pharmacological Phenomena

2024
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...

The Wave Nature of Light

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion. Others in the...

In this video we first describe fabrication and operation procedures of a surface acoustic wave (SAW) acoustic counterflow device. We then demonstrate an experimental setup that allows for both qualitative flow visualization and quantitative analysis of complex flows within the SAW pumping device.
FAQs
Superposition allows overlapping disturbances to combine, so their interaction can produce interference. The resulting pattern depends on how the contributing waves combine at each location, making interference useful for examining relationships among waves rather than treating each disturbance independently. In physics, this principle helps interpret observed patterns in sound, light, and other wave-based systems.
These properties describe different aspects of wave behavior and energy transport. Wavelength characterizes spatial repetition, frequency describes temporal repetition, amplitude indicates the size of the oscillation, and speed describes propagation through space or a medium. Considering them together enables researchers to compare waves and interpret how their behavior changes during interactions.
Reflection, refraction, and diffraction represent distinct interaction behaviors. Reflection concerns a wave returning from an interaction, refraction concerns its change as it passes through an environment, and diffraction concerns the way wave behavior responds to constraints or openings. Distinguishing these effects helps physicists interpret how waves interact with materials and surrounding environments.
A useful analysis begins by identifying the relevant wavelength, frequency, amplitude, and propagation speed. Researchers can then examine whether the observed behavior includes interference, diffraction, reflection, or refraction. Comparing these features with the wave’s environment helps reveal how energy is transported and how the system responds to its surroundings.
Wave principles support a broad range of applications, including acoustics, optics, electromagnetic communication, and seismic sensing. In each case, researchers interpret propagation and interactions to obtain useful information or transmit energy. The same underlying concepts therefore connect the study of sound and light with communication systems and methods for investigating Earth-related signals.
Wave behavior provides a framework for interpreting how energy moves and interacts with environments, while also contributing to the study of matter and quantum behavior. Applying these principles supports imaging and telecommunications technologies and helps researchers extract information from wave interactions. Physics uses this shared framework to connect fundamental research with practical measurement and communication systems.
