Answers
Answer:
In Diamond speed of light will be lowest while in water it is will be highest
Explanation:
Answer:
The speed of the light will be highest in water and lowest in Diamond.
Explanation:
Refractive index:
The refractive index is defined as the difference between the speed of light in a vacuum and that in a medium. The speed of light is slowed down when it travels through a medium other than the vacuum because the atoms in that material constantly absorb and reemit light particles.
Formula:
Refractive index of the medium = Speed of light in air / Speed of light
in the medium
Therefore,
Speed of light of the medium = Speed of light in air / Refractive index
in the medium
Since Speed of light in air is always constant
Hence,
Speed of light in the medium = Constant / Refractive index of the
medium
Hence
Lower refractive index of the medium, the higher is the speed of light
According to the formula,
- Water has the lower refractive index
- Diamond has the highest refractive index
Finally In Water the speed of light is highest and in Diamond the speed of the light will be lowest.
Final answer:
The speed of the light will be highest in water and lowest in Diamond.
