What is an undulating motion?
verb (used without object), un·du·lat·ed, un·du·lat·ing. to move with a sinuous or wavelike motion; display a smooth rising-and-falling or side-to-side alternation of movement: The flag undulates in the breeze. to have a wavy form or surface; bend with successive curves in alternate directions.
What is Undulatory propulsion?
Undulatory locomotion is the type of motion characterized by wave-like movement patterns that act to propel an animal forward. Examples of this type of gait include crawling in snakes, or swimming in the lamprey.
How does Undulatory locomotion work?
Undulatory locomotion is a means of self-propulsion that relies on the generation and propagation of waves along a body. As a mode of locomotion it is primitive and relatively simple, yet can be remarkably robust.
What is oscillatory swimming?
Oscillatory swimmers, such as salmon, tuna, dolphins and sharks, propel themselves primarily using a semi-rigid caudal fin or fluke that is oscillated periodically.
What is the meaning of Undulatory?
: of or relating to undulation : moving in or resembling waves : undulating.
What is undulated land?
A short definition of Undulating Land: Rolling land composed of compound slopes (two or more slopes of different grades).
What is caudal oscillation?
Many marine mammals and fish propel themselves with oscillations of the posterior body (termed caudal-oscillatory swimming which includes thunniform and sub-carangiform swimming styles).
What is the difference between undulate and oscillate?
As verbs the difference between oscillate and undulate is that oscillate is to swing back and forth, especially if with a regular rhythm while undulate is to cause to move in a wavelike motion.
What does Underlation mean?
1a : a rising and falling in waves. b : a wavelike motion to and fro in a fluid or elastic medium propagated continuously among its particles but with little or no permanent translation of the particles in the direction of the propagation : vibration.
What are the two meanings of spruce?
: neat or smart in appearance : trim. spruce. noun. plural spruces also spruce.
What is the meaning of Dulating?
1 : to form or move in waves : fluctuate. 2 : to rise and fall in volume, pitch, or cadence.
When did Hans Motz invent the first undulator?
Hans Motz and his coworkers at Stanford University demonstrated the first undulator in 1952. It produced the first manmade coherent infrared radiation. The design could produce a total frequency range from visible light down to millimeter waves.
When is an undulator no longer called a undulator?
If the oscillation amplitude is bigger and the radiation contributions from each field period sum up independently, leading to a broad energy spectrum. In this regime of fields the device is no longer called an undulator; it is called a wiggler .
What kind of magnetic field is an undulator?
Undulator. An undulator is an insertion device from high-energy physics and usually part of a larger installation, a synchrotron storage ring, or it may be a component of a free electron laser. It consists of a periodic structure of dipole magnets. The static magnetic field alternates along the length of the undulator with a wavelength .
How is the strength of an undulator determined?
The undulator strength parameter is: where e is the electron charge, B is the magnetic field, λ u {displaystyle lambda _{u}} is the spatial period of the undulator magnets, m e {displaystyle m_{e}} is the electron rest mass, and c is the speed of light. This parameter characterizes the nature of the electron motion.
