The soft, gentle breezes affect her disposition.
2. To pretend, to feign: Although Joy is from New York; as an actress, she had to affect a British accent.The soft gentle breezes have an effect on Marvin's disposition.
2. Influence, power, force: The plea for clemency had no effect on the judge.2. To produce, to accomplish, to bring about: Does the new hairdo effect Lydia's appearance?
The affect of the curve ball did not effect the batter's hitting a home run.
2. Actuality, fact, reality, truth; significance, meaning, gist, general idea; implication, essence, drift, tenor: "In effect, her insult meant the end of our friendship."
3. Influence, power, force, effectiveness, efficacy, impact, impression, weight, validity: "The plea for clemency had no effect on the judge."
4. Personal property, possessions, things, goods, movables, furniture, trappintgs; personal estate, commodities, holdings, assets, chattels: "Before they moved, the family had to sell as many of their effects as possible."
5. As a verb; to produce, to accomoplish, to bring about, to make, to cause, to achieve, to carry out, to execute, to perform, to create, to realize, to attain: "The new hairdo effected a startling change in her appearance."
Usage note: When you affect anything, you have an effect on it. As a verb, affect means to influence; as a noun, effect means the same thing. The big difference comes when you use effect as a verb because its meaning then becomes accomplish or execute: "The little boy’s tears affected her deeply and they effected the desired result, because she forgave him."
This gives way abruptly if the pressure to produce flexion is continued.
2. An initial marked resistance to passive movement, which then suddenly gives way.This variety of increased muscle tone is characteristic of spasticity as a result of disease or dysfunction of the pyramidal tracts.
2. The effect of an electric field on spectrum lines.
The electric field may be externally applied; but in many cases it is an internal field caused by the presence of neighboring ions or atoms in a gas, liquid, or solid.
The free electrons then free others in the same manner, etc.
2. The cumulative process in which an electron (or other charged particle) accelerated by a strong electric field collides with and ionizes gas molecules, thereby releasing new electrons which in turn have more collisions, so that the discharge is self-maintained.The effect can be used to modulate a light beam in a material since many properties; such as, light-conducting velocities, reflection, and transmission coefficients at interfaces, acceptance angles, critical angles, and transmission modes, are dependent on the refractive indexes of the media in which the light travels.
2. Birefringence induced by an electric field or an optical property in which a single ray of unpolarized light splits into two components traveling at different velocities and in different directions.
In birefringent materials either the separation between neighboring atomic structural units is different in different directions, or the bonds tying such units together have different characteristics in different directions.
2. The change in the index of refraction of a material when subjected to an electric field.
The effect can b used to modulate a light beam in a material since many properties; such as, light-conduction velocities, reflection, and transmission coefficients at interfaces, acceptance angles, critical angles, and transmission modes, are dependent on the refractive indexes of the media in which the light travels.
3. Audible clicks induced by pulsed or modulated microwave frequencies.
The clicks are generated directly inside the human head without the need of any receiving electronic device.
2. A retarding effect on the characteristic motion of an ion in an electrolytic solution subjected to a potential gradient, that results from a motion in the opposite direction by the ion atmosphere.
2. The change in the resistivity of certain materials with changes in applied voltage.
This is the opposite of that which is created between the two terminals of the loop.
2. The change in viscosity of a liquid when placed in a strong electrostatic field.
The effect is very small and occurs only in polar liquids.
In double refraction, the index of refraction (a measure of the amount the ray is bent on entering the material), and hence the wave velocity of light vibrating in the direction of the electric field, is slightly different from the index of refraction of the vibration perpendicular to it.
Optically, the substance behaves like a crystal with its optic axis parallel to the electric field.
This effect was discovered in the latter part of the 19th century by a Scottish physicist, John Kerr.
The same behavior in solids is sometimes called the Pockels effect.
The term nocebo; Latin for "I will harm", was chosen by Walter Kennedy, in 1961, to indicate the counterpart of one of the more recent applications of the term "placebo" which means, "I will please", namely that of a placebo being a drug that apparently produced a beneficial, healthy, pleasant, or desirable consequence in a subject, as a direct result of that subject's beliefs and expectations.
The classical concept of light as a continuous wave could not account for this, and it was then explained by Einstein (1905) on the basis that light is a stream of separate particles.
This interpretation, and his subsequent elaboration of it, is said to have formed the basis for much of quantum mechanics.
When this property of light is combined with the properties of semiconductors, electrons flow in one direction across a junction, setting up a voltage.
With the addition of circuitry, current flows and electric power is available.
2. An electromechanical effect by which mechanical forces acting upon a ferroelectric material can produce an electrical response, and electrical forces can produce a mechanical response.
2. An effect created as the total phase of a solar eclipse is about to begin, when the last Baily's bead, a remaining bit of phosphere, glows so intensely by contrast with the sun's faint corona that it looks like the jewel on a ring.
It also refers to the equivalent phase at the end of totality.
2. The shift of spectral lines due to a body's motion toward or away from an observer.
Astronomers can tell by the Doppler effect if a distant star is moving toward or away from us.
3. A perceived change in the frequency of a wave as the distance between the source and the observer changes; for example, the sound of a siren on a moving vehicle appears to change as it approaches and passes an observer.4. Etymology: named after Christian J. Doppler (1803-1853), an Austrian physicist and mathematician who first described the principle known as the Doppler effect in 1842.
Doppler observed that the frequency of light and sound waves is affected by the relative motion of the source and the detector.
Another example is that of a train which approaches an observer, and a lower pitch after it passes by. The Doppler effect applies to all types of waves, including light.
This effect occurs on Venus and on Earth.
A simple example is social facilitation, in which an activity increases merely from the sight or sound (or other form of stimulation) coming from other individuals engaged in the same activity.
When this property of light is combined with the properties of semiconductors, electrons flow in one direction across a junction, setting up a voltage.
With the addition of circuitry, current will flow and electric power will be available.
2. An effect in which the penumbra of a sunspot appears narrower in the direction toward the sun's center than in the direction toward the sun's limb.
In 1769, a Scottish astronomer named Alexander Wilson noticed that the shape of sunspots noticeably flattened as they approached the Sun's limb due to the solar rotation.
