Is there any relation between boiling point and refractive index?

No, there is no direct relationship between the boiling point and refractive index of a substance. Boiling point is a physical property related to the temperature at which a substance changes from a liquid to a gas, whereas refractive index is a measure of how light propagates through a material.


What is the referactive index of contact lens?

The refractive index of contact lenses typically ranges from about 1.40 to 1.50, depending on the material used. Soft contact lenses, often made from hydrogels or silicone hydrogels, generally have a refractive index around 1.42 to 1.46. Rigid gas-permeable lenses can have a slightly higher refractive index, around 1.48 to 1.50. The specific index can vary based on the lens's design and intended use.


Would heptane be a solid at 100 K?

Heptane is a gas at 100 K.


Is heptane a gas?

Yes, heptane is a colorless liquid at room temperature. It is a hydrocarbon compound with the chemical formula C7H16.


If the temperature of heptane increased from 90 degrees to 100 degrees would a physical or chemical change take place?

The temperature increase from 90 to 100 degrees for heptane would not cause a chemical change. It would only result in a physical change, such as a phase change from liquid to gas.


How can the speed of a light wave be changed?

The speed of a light wave can be changed by traveling through different mediums with varying refractive indexes. When light enters a medium with a higher refractive index, it slows down, and when it exits to a medium with a lower refractive index, it speeds up. This change in speed is due to the interaction of light with the atoms in the medium.


What is the chemical compose of ozone layer?

Ozone has molecula formula O3. Its molar mass is 48 g/mol. It is a pale blue coloured gas. Its density is 2.144mg cm-3. Its refractive index is 1.2226.


Will the wavelength of a light wave will increase as it moves from a gas into a liquid?

No, the wavelength of a light wave will not change as it moves from a gas into a liquid. The wavelength of light is determined by the material through which it is propagating, so it will remain constant unless the light enters a different medium with a different refractive index.
