Crystaline sugar (sucrose) has a refractive index of around 1.56. Sugar solutions can have refractive indices greater than this. Note, that the refractive index of a substance can even be determined for opaque substances. This is because the RI also determines reflective properties. So by measuring the amount of light reflected by light shining on a polished sample at a given angle, a refractive index can in principle be obtained.
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.
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
Also 1.5. That's how the index of refraction is defined.
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
The index of refraction.
Index Of Refraction
Q: How do you think increasing a medium's index of refraction might affect the angle of refraction?
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.

well kids, the answer is INDEX OF REFRACTION. (: science question on my homework
c divided by the index of refraction of the medium = the speed of light in the medium.
Water's index of refraction is 1.333
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.
Approximately 1
The ray of light bends towards the normal.
