Shear waves oscillate perpendicular to the direction of travel, while longitudinal waves oscillate in the same direction. Transverse waves can be composed of matter or energy, while electromagnetic waves can use empty space as a medium. Longitudinal waves propagate through a gaseous medium, while shear waves can be made with matter or through shear stress […]
Seismic waves, caused by explosions, wind, or ocean waves, can cause serious damage. Seismology studies earthquakes and waves, and seismologists interpret the Earth’s composition and assess potential dangers. Body waves include P-waves and S-waves, while surface waves cause the most destruction. Seismologists use seismographs to measure waves and predict future events. A seismic wave is […]
A standing wave is formed by two identical waves moving in opposite directions, causing energy to interfere and create a wave that appears to vibrate in place. The energy, not the medium, travels in a wave. The amplitude of a standing wave remains in the same place, with nodes canceling out opposing movements and antinodes […]
Rogue waves, previously thought to be mythical, are real and can reach heights of up to 25m, posing a threat to large vessels. They have been a part of sailor stories for centuries and are now an important area of study for oceanographers and physicists. The causes of rogue waves are still being studied, but […]
Pulse wave velocity measures arterial stiffness noninvasively by analyzing blood flow and arterial elasticity. It can diagnose and monitor vascular diseases such as hypertension. The method measures the flexibility or stiffness of the aorta and can detect high blood pressure, hardening of the arteries, and blood circulation disorders. Pulse wave velocity is a method used […]
A sine graph shows y = sin x, repeating along the x-axis with a period of 1.0π. The sine, cosine, and tangent represent ratios of a right triangle, with the sine having a reciprocal called the cosecant. A unit circle can help visualize sine values at different angles. Sine waves are found in math, physics, […]
Wave pools work like modern flush toilets, with two compartments and a hydraulic piston pushing out water to create waves. The pools are efficient and recycle water, but the waves must be dissipated to prevent injury. It’s not often that the perfect analogy falls into place, but in the case of wave pools, we have […]
A sine wave generator produces oscillating frequencies in a sine wave pattern, useful for measuring sound or electrical frequency. Sine waves are smooth and even, and can be used to calibrate measuring equipment and generate sound effects. Function generators can produce other waveforms, such as square waves, which are used in digital electronics. A sine […]
Wave patterns show wave height, direction, and swell propagation. Data comes from buoys, weather observations, and satellites. Color and vectors indicate sea state and swell period. Physics and storm tracking also affect wave models. Predicting tropical systems is difficult. A wave pattern is a representation of how high the waves are, where they are heading, […]
Longitudinal waves move parallel to the direction of motion and transmit energy through a medium. Non-electromagnetic waves include pressure and sound waves, while electromagnetic waves can transmit energy through a vacuum. P-waves are the fastest seismic waves and are recorded by seismometers. Sound waves require a medium to travel and travel faster in solid media. […]
Wave power harnesses the energy of ocean waves to generate electricity. It is a renewable and relatively cheap energy source that can power various operations. The technology uses chambers that capture air pushed by waves to spin turbines. Critics are concerned about the visual impact and noise, but proponents hope the benefits will outweigh the […]
A sawtooth wave has ramps that drop off or start abruptly, resembling the teeth on a saw. It is used in music synthesizers and visual applications, and has no symmetry. A sine wave, in its simplest form, is a wave that has a fixed frequency and wavelength, and is very reminiscent of the images most […]
Full-wave rectification converts AC electrical energy into DC using diodes. A bridge rectifier allows both positive and negative halves of the AC wave to pass, resulting in a smoother DC signal. Voltage regulators can be used for further smoothing. Full-wave rectification is a process of converting alternating current (AC) electrical energy into a direct current […]
Acoustic waves are pressure swings that transmit sound through solid, liquid, or gas. They are defined by wavelength, frequency, and amplitude. The ear collects sound waves, which vibrate the eardrum and three tiny bones in the middle ear. The vibrations are transformed into electrical impulses that the brain interprets as sound. Hair cells in the […]
Elastic waves travel through materials or fluids without causing permanent changes. They can be analyzed mathematically and visualized using graphs. They can be captured using ultrasound cameras or lasers. Different materials exhibit separate propagation patterns. An elastic wave generally travels through a material or fluid, or on its surface, without causing any permanent structural or […]
Elliott Wave Theory is a technical analysis used to predict stock market trends by monitoring price wave patterns and collective psychology. It divides waves into impulse waves and corrective waves, which repeat in cycles of different time scales. It works on probabilities and is a careful and mathematical way of exploiting the odds in favor […]
The Elliott Wave principle is a technical analysis of stock and commodity markets, based on charting market cycles using behavioral economics. It divides market cycles into Impulse and Corrective Waves, with further wave structures. The theory is reliable and still widely accepted today, and was formulated by Ralph Nelson Elliott in the 1930s. The Elliott […]
