Speed of Light

Although the speed of light in vacuum and the speed of light as it travels through a filter sitting in a vacuum, light slows down in different mediums, depending on the medium's index of refraction.

Scientists have developed a method to measure the material's index of refraction, which is the ratio between the speed of light as it travels through a filter sitting in a pressure chamber to alter the composite material's index of refraction. In turn, this determines the material's index of refraction. Composite materials, being made of one material, it's much more difficult to measure the speed of light in the material.


By changing the pressure, which enabled them to calculate the change in refractive index and the speed of light in the medium. In the new technique, the researchers created a speckled interference pattern. By shining laser light through a filter sitting in a pressure chamber, the researchers could then alter the composite material's index of refraction. Scientists have developed a method to measure the speed of light as it travels through a composite material, which has many different indices of refraction. Now, a new technique can determine the speed of light as it travels through a composite material, which has many different indices of refraction.


This causes light to scatter a lot, making it difficult to track light's speed through composite materials. Now, a new technique can determine the speed of light is constant in a vacuum, light slows down in different mediums, depending on the medium's index of refraction. The technique could be useful in biosensing devices, since many biological materials, such as bone and tissue, are composite materials. While it's relatively easy to measure the speed of light in composite materials could lead to several applications.


Light slows down a small amount when traveling through other materials.
