yes
It is because the index is related to the velocity of light in air (ideally vacuum) and the medium in question. Since the velocity of light in vacuum is greater than it can be in any other media, the index of refraction of these other media relative to the vacuum is greater than 1.However, if you studied light travelling through glass and then water, the index of refraction between those two would be 0.89 (approx).
Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index
Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.
Both can be calculated easily using Snell's Law, which you can find easily online. However to use Snell's law you will need one of the angle of incidence or refraction as well as the refractive index of the media the light ray passes through
This is called the index of refraction. When light crosses the boundary between mediums (media) with different indices, it is bent (refracted).It's usually defined the other way around ... the ratio of the speed of light in vacuum to its speed in the medium. Since the speed of light is greater in vacuum than in any medium, the number is always greater than 1. It's referred to as the "refractive index" of the medium.
The ratio of speed of light in a given pair of media , gives us a measure of the extent of refraction of a ray of light as it goes from one medium to another. We use this ratio to define a term called the relative refractive index for a given pair of media . A relative refractive index is light that passes from one transparent medium to another.
The answer depends on the refractive index of the media.

Refractive index is defined as the ratio of the speed of light in vacuum to the speed of light in given media.
1Ideally speaking, the ratio of the sines of the angles of incidence and refraction will be the same if the medium is the same. So the refractive index will be 1.However, refractive index is, again, a relative value. If we say that the refractive index of glass is 1.5, it implies that the refractive index of glass, with respect to air is 1.5. So the value might change based on the media involved in refraction.It can also be safely concluded, without much Physics, that any multiplicative quantity for the standard element will be 1. (ex: speed of sound is Mach 1)
index of refraction ( or refractive index)
When light passes from one medium to another with a different refractive index, andnot in a direction perpendicular to the boundary between the media, its speed changes.
The skin by its refractive index with respect to its other media is a Fresnel interface; at the interface white is scattered.
that depends on the refractive index of the surface refracting the light beam. This is also affected by the light's wavelength and temperature of the media. Sage.
No. Without refraction at a boundary between media with different refractive indices, lenses wouldn't work. The only way we would have of forming real images would be with curved mirrors.
In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities. A surface wave can also be an electromagnetic wave guided by a refractive index gradient. ...
Lenses operate on having another index than the immediate surrounding. Sink a lens in a media with the same index and it won't work. It'll be like it's all glass.
