What is relative refractive index?
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.
What do you mean by refractive index and what are factor in which it depends?
Refractive index is defined as the ratio of the speed of light in vacuum to the speed of light in given media.
What is refractive index of AIR?
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)
When a light wave enters into a medium of different optical density?
index of refraction ( or refractive index)
What is a suface wave?
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. ...
Can relative refractive index between 2 media be less than unity?
yes

What is the speed of light in media?
The answer depends on the refractive index of the media.

What happens when speed of light enters a new kind of medium?
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.
Why do bubbles in water look shiny?
The skin by its refractive index with respect to its other media is a Fresnel interface; at the interface white is scattered.
In what direction does light turn when it refract?
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.
If the speed of light was the same in all materials would a lens cause light rays to bend?
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.
