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.
Refractive index is determined by measuring the angle of refraction through a prism or by calculating the ratio of the speed of light in a vacuum to the speed of light in the material. This can be done using Snell's Law or by observing the bending of light as it passes through different mediums.
Galileo attempted to measure the speed of light using lanterns positioned at known distances and observing the time it took for light to travel between them. He would uncover the lanterns simultaneously and use a telescope to try and detect any delay in the light reaching his eyes. However, his methods were not sensitive enough to accurately measure the speed of light.
The speed of light in quartz is approximately 186,282 miles per second, which is slower than the speed of light in a vacuum. The slowing down of light in a medium like quartz is due to its refractive index, which affects the speed at which light travels through the material.
The speed of light was first measured in 1676 by Danish astronomer Ole Rømer using observations of the moons of Jupiter. Rømer's work provided the first quantitative estimate of the speed of light.
The speed of sound can be determined using the formula: speed = frequency x wavelength. Frequency can be measured using a sound wave device like a microphone, while wavelength can be measured by calculating the distance between two sound wave peaks. This method allows for the accurate determination of the speed of sound in a specific medium.
Refractive index is determined by measuring the angle of refraction through a prism or by calculating the ratio of the speed of light in a vacuum to the speed of light in the material. This can be done using Snell's Law or by observing the bending of light as it passes through different mediums.
The speed of a moving object can be measured by calculating the distance the object travels over a specific period of time. This can be done using the formula: speed = distance / time. Alternatively, speed can also be measured using radar guns or GPS devices that track the object's movement in real-time.
Speed can be expressed using any unit of distance and time. Eg. 1 yard per second = 2.0454 miles per hour.
You can detect the speed of a ball by using tools like radar guns, speed cameras, or by calculating the speed based on time and distance measurements. These methods can provide an accurate measurement of the ball's speed at a given moment.
Nothing can travel at the speed of light, only light itself, the closest we have ever gotten to the speed of light is 99.9 %, we have accelerated particles at very very close to the speed of light using the LHC (Large Hadron Collider). The only thing that can go faster than the speed of light, is Space.
A superhero travels at the speed of light by using their powers they obtained by birth, chemical reaction, or other reason.

He would uncover the lanterns simultaneously and use a telescope to try and detect any delay in the light reaching his eyes.

We generally consider that the force of an electric field moves at the speed of light. And electricity moves at the speed of light.

A few on-line resources all cluster around roughly 217,400,000 meters per second.Note: The speed of light doesn't depend on where the light comes from.
