I'll assume that this is the critical angle from the median to a vaccum.
You use Snell's law, n1sin(x1) = n2sin(x2)
where n1 = index of refraction of your median, n2 = 1 (the index of refraction in a vaccum), x1 = the critical angle (45 degrees), x2 = 90 degrees since light comes out at 90 degrees when it is shone on the critical angle.
So...
n1sin(45 degrees) = 1 (sin 90 = 1)
n1 = 1/sin(45 degrees)
n1 = 1.414...
Now the index of refraction is the speed of light in a vaccum over the speed of light in the median so:
1.414... = (3.00 x 10^8 m/s) / v
v = (3.00 x 10^8 m/s) / 1.414...
v= 2.1 x 10^8 m/s
speed of light I think well it sounds right:)
The Quran does not contain a specific calculation for the speed of light. The speed of light in a vacuum, approximately 299,792 kilometers per second, was not known or measured at the time of the Quran's revelation. The Quran is not a scientific textbook but rather a religious text providing guidance for believers.
No, it is not possible to travel at the speed of light in water. Light travels at a slower speed in water compared to its speed in a vacuum, which is about 299,792 kilometers per second. The speed of light in water is approximately 225,000 kilometers per second.
The speed of light is much greater than the speed of sound.
The speed of light does not have a temperature.

The velocity of light in vacuum is 299,792,458km/s, for daily calculation it's considered as 300000km/s, so put the distance and "C"(velocity of light) in speed and distance equation and you will get the answer.[time=distance/speed]"atul ashish"
Strange as it may seem, the speed of all electromagnetic waves was predicted longbefore it was ever measured. After the speed was predicted, measurements of light-speed supported the growing suspicion that light is electromagnetic radiation, becausethe measured speed was so close to the predicted speed.Measuring the speed of light is not easy, and several clever methods had to be inventedin order to do it. Calculus was almost certainly used at many points in the applicationof these methods.
Calculation for speed
it should be 3x10^8 m s^(-1). here is the calculation: we have known that the refractive index of vacuum is 1, by n= v/c ( n stands for refractive index of medium, v stands for the speed of light in medium, c stands for speed of light constant) 1=v/3X10^8 m s^(-1) v= therefore, speed of light in vacuum is 3x10^8 m s^(-1) actually, all light ray in electromagnetic spectrum have same speed in vacuum

Is what the speed of light or light speed.ANSWER300,000 km/s
You can't go that fast. That would be faster than the speed of light. Anyway, for a hypothetical calculation, divide the distance by the speed.

speed of light
In light speed.
Perhaps coincidentally, the phrase "light speed" refers to a speed.It is a speed.
