The act of refracting, or the state of being refracted., The change in the direction of ray of light, heat, or the like, when it enters obliquely a medium of a different density from that through which it has previously moved., The change in the direction of a ray of light, and, consequently, in the apparent position of a heavenly body from which it emanates, arising from its passage through the earth's atmosphere; -- hence distinguished as atmospheric refraction, or astronomical refraction., The correction which is to be deducted from the apparent altitude of a heavenly body on account of atmospheric refraction, in order to obtain the true altitude.

How is a miterial's index of refraction related to its optical density?
A material's index of refraction is related to its optical density through Snell's Law, which relates the angles of incidence and refraction as light passes through the interface between two materials with different refractive indices. A higher index of refraction usually corresponds to a higher optical density, meaning that light travels slower through the material.
Does meaning of normal change when representing refraction?
In the context of refraction, "normal" refers to an imaginary line perpendicular to the surface at the point where the light ray hits. It is used as a reference point to determine angles of incidence and refraction. The concept of "normal" remains the same in this context as it is used in optics to describe the behavior of light waves.
Does emerald have double refraction?
No, emerald does not exhibit double refraction. It is a type of beryl that is typically a single crystal structure, meaning it has isotropic properties. Double refraction is characteristic of birefringent materials, where light splits into two rays when passing through. However, some other minerals, like calcite, do display this phenomenon.
What is it called when a wave goes from one medium to another and it changes speed and direction?
It is called refraction. Refraction occurs when a wave changes speed and direction as it travels from one medium to another, due to the change in its wave velocity and the change in the medium's optical density.
Which is better reflection or refraction?
Refraction is better.
What is the suffix for refraction?
The suffix for refraction is "-tion".
How does the angle of refraction change as the index of refraction of the bottom material increases?
As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.
