At Divergent boundaries two plates split and tear apart moving away from one another, while at Convergent boundaries plates moves toward each other from opposite directions.
What else can I help you with?
A light beam striking a concave inward curve mirror reflects and?
converges towards a focal point if the light is emitted from the focal point or beyond it. If the light source is located between the mirror and the focal point, the reflected light diverges.
What is unit of measurement of a lens refractive power?
diopter
When does a convex lens act as a diverging lens?
A convex lens acts as a diverging lens when the light passing through it diverges rather than converges. This typically occurs when the object is located very close to the lens or when the light rays are not parallel to begin with.
What type of device forms images by changing the direction but not the speed at which light travels?
A lens is the type of device that forms images by changing the direction but not the speed at which light travels. This is achieved through refraction, where the bending of light rays converges or diverges to create an image.
What do convex and concave lens do?
A convex lens converges light rays to a focal point, used to correct hyperopia (farsightedness) or create magnification in optical devices. A concave lens diverges light rays, used to correct myopia (nearsightedness) or reduce image size in optical systems.
How do you tell if a geometric series diverges or con verges?
If the absolute value of the common multiple is less than 1 then it converges and, if not, it diverges.
What is a sequence that converges to 0 but the series diverges?
harmonic series 1/n .
What is D'Alembert's ratio test?
D'Alembert's ratio test, or simply the ratio test, is a way of determining whether certain series converge. It goes like this: to check if a series converges, check the sequence of ratios between consecutive terms. If that sequence converges to something less than 1, then the series converges absolutely. If it converges to something greater than 1, or diverges, then the series diverges. If it converges to 1 exactly, then the test is inconclusive.
What are crystallens lenses on ray-ban sunglasses?
Crystallens lenses on Ray-Ban sunglasses are optical devices. These transmit and refracts light which converges and diverges the beam.
A light beam striking a concave inward curve mirror reflects and?
converges towards a focal point if the light is emitted from the focal point or beyond it. If the light source is located between the mirror and the focal point, the reflected light diverges.
What is unit of measurement of a lens refractive power?
diopter
What is converging in calculus?
In calculus, you say that a series or integral converges if it has a finite value. If it does not converge, the series or integral usually diverges to infinity (that is, it does not have a finite value such as 3, -8, 67 etc.,)
What is a refracting device called?
A refracting device is called a lens. It is an optical device that is designed to refract light in a way that converges or diverges the light rays to create an image.
What is the comparison test for series?
The comparison test states that if a series of positive numbers converges, and in another series, each of the corresponding terms is smaller, then it too must converge. Similarly, if a series of positive numbers diverges to infinity, and another series has each of its terms greater than the corresponding terms of the other, then it too diverges.
When does a convex lens act as a diverging lens?
A convex lens acts as a diverging lens when the light passing through it diverges rather than converges. This typically occurs when the object is located very close to the lens or when the light rays are not parallel to begin with.
What is the positive lens is the same as?
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
What type of device forms images by changing the direction but not the speed at which light travels?
A lens is the type of device that forms images by changing the direction but not the speed at which light travels. This is achieved through refraction, where the bending of light rays converges or diverges to create an image.
