The speed of light in air is around 299,705 kilometres per second or 2.99705 × 10 8 m / s . Light travels at a constant speed of 2.99792 × 10 8 m / s in ...

Speed of light in air is 3×108 m/s and speed of light in common glass is 2×108m/s.Calculate the refractive index of glass.

The speed of light in air is 3 ×108ms−1. Calculate the speed of light in glass. The refractive index of glass is 1.5.

The speed of light is 3×108 ms−1 in vacuum or air, 2.25×108 ms−1 in water and 2×108 ms−1 in glass.

The correct answer is 2 × 108 m/s. CONCEPT: Refractive index: The ratio of the speed of light in a vacuum to the speed of light in a medium is c.

12 авг. 2020 г. · The speed of light in air is approximately 3.00 × 108 m/s, equivalent to its speed in a vacuum. The speed of light in polystyrene is slower due ...
