Determine the speed of light in glass. refractive index of glass 1.5
| September 18, 2021 | education
Data: n (glass refractive index) = 1.5; C (speed of sunlight) = 3 * 10 ^ 8 m / s.
To find the speed of light in glass, we apply the formula: n = C / Vst, from where we express: Vst = C / n = 3 * 10 ^ 8 / 1.5 = 2 * 10 ^ 8 m / s.
Answer: The speed of light in glass, according to the calculation, is 2 * 10 ^ 8 m / s.
