WebUnder the present definition of the kilogram, which states that "The kilogram [...] is defined by taking the fixed numerical value of h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, … WebJan 17, 2024 · The speed of light in water is given as 2.25×10 8 m/s and in glass it is around 1.95×10 8 m/s. I assume that speed of light in a certain material could be stated as c=1/√ (εμ). It looks like one cannot write c=1/√ (εμ) because as you can see and as was expected that calculated value of speed of light in glass is lager than that of water.
