(1) The speed of light in air is 3.0 × 10^8m/s. Its speed in the glass is 2.0 × 10^8m
7 (a) The speed of light in air is 3.0 × 108m/s.The speed of light in a transparent liquid is 2.0 × 108m/s. A ray of light is incident on the surface of the liquid at an angle of incidence of 40°.Calculate(i) the refractive index of the liquid,refractive index = ....
The speed of light in air is around 299,705 kilometres per second or2.99705×108m/s. Light travels at a constant speed of... Learn more about this topic: Refraction & Dispersion: Definition, Snell's Law & Index of Refraction from
The light travels as a wave with a definite speed. This speed varies if the medium of travel changes in its path. The speed of light gets slower if the medium is denser. The fastest speed of light is in the vacuum, c=3×108 m/s ...
To calculate the speed of light in glass, we can use the relationship between the speed of light in different media and the refractive index. The refractive index (n) is defined as the ratio of the speed of light in a vacuum (or air, approximately) to the speed of light in the medium...

a) 1.5 b) 1.2 c) 0.8The speed of light in air is 3 xx 10^(8) m/s. IN medium X its speed is 2 xx 10^(8) m/s and in medium Y the speed of light is 2.5 xx 10^(8)m/s. Calculate: a) .("air")n(X) b) .(x)n(y)
(创新题) Which is faster in the air, the speed of light or the speed of sound? A. Light. B. Sound. C. Both. D. Neither. 相关知识点: 试题来源: 解析 A 考查物理常识。句意为:空气中光速和声速哪个更快?根据基础的物理知识可知真空中光速为3*10^8m/s,而声速为340m/s。故选A。
Now let us demonstrate that the principle of least time will give Snell's law of refraction. We must, however, make an assumption about the speed of light in water. We shall assume that the speed of light in water is lower than the speed of light in air by a certain factor,n. ...
What is the speed of light in diamond if its refractive index is 2.41 ? View Solution (a) The refractive index of glass is 1.5. What is the speed of light in glass? (b) Is the speed of light in glass independent of the colour of light ? If not, which of the two colours red an...
