Question

what is the speed of light in a medium of refractive index 1.4 if its speed is 3,00,000km/s?​

Answer 1

Explanation:

Hydrometallurgy is concerned with processes that use aqueous solutions to extract metals from ores. The most common hydrometallurgical process is leaching, ...

answe I don't

Answer 2

Answer:

The refractive index can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values: the speed of light in a medium is v = c/n, and similarly the wavelength in that medium is λ = λ0/n, where λ0 is the wavelength of that light in vacuum.

Explanation:

1.8=300000÷speed of light in that medium

speed of light in medium=300000÷1.8=166666.667
