The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
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 index of refraction.
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).
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.
