Fizeau(french physicist) method, Foucault method, and Michelson method are the most important experiments that were done.
It is very hard in laboratory to measure the absolute speed of light.
But if we accept the value of speed of light in air, then we can use snell's law of refraction to find the speed of light in another medium.
I am describing that here:
Suppose light enters from air to another medium.
Then absolute refractive index(RI) of medium = sin(i) / sin(r)
RI = c/v
Where i = angle of incidence
r = angle of refraction
C = speed of sound in air or vaccum(both are almost same)
V = speed of sound in medium.
Using these two equations we can find speed of sound in the given medium
What else can I help you with?
Write an experiment to find the velocity of sound?
Write an experiment to find the velocity of sound?
Can any object move with the velocity comparable to the velocity of light?
Recently an experiment at the CERN has clocked a Neutrino that they believe EXCEEDED the speed of light. They are double checking the results of this experiment, and looking for explanations.
How coud you find the wavelenght of light you knew its speed and frecucey?
wavelength = velocity / frequency
What is the velocity of light in meters?
the velocity of light is 300000000 m/s
Who invented light travels faster than sound?
The velocity of light was found by many scientists using different techniques. First Romer found the velocity of light by observing the eclipse and so he followed astronomical facts. First lab experiment done by Foucault. Due to some kind of limitations, later Michelson followed some precise method. Just by comparing the velocity of light with that of sound, we come to know that the former is much greater.
Is the speed of light breakable?
Information -- and that includes anything with mass -- can not be transmitted from one point to another with a velocity greater than the speed of light. Despite innumerable attempts, no experiment has found a way around this fact of our Universe.
What would be the velocity of ball which is thrown by the man who running at the speed equal to the velocity of light?
As velocity never exceeds the velocity of light.... so i hope a man running with the velocity of light will not be able to throw a ball with any velocity.......... we may get the maximum n minimum velocity with which that can be thrown mathematically that we may get it to be zero................
Is the velocity of a red light lower than the velocity of violet light a?
Not necessarily, but the frequencies are different.
Is the velocity of a red light lower than the velocity of violet light?
No it justs refracts further
Does Light have a speed or a velocity speed of light or velocity of light?
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
How to calculate velocity after collision in a physics experiment?
To calculate velocity after a collision in a physics experiment, you can use the conservation of momentum principle. This involves adding the momentum of the objects before the collision and setting it equal to the momentum of the objects after the collision. By solving this equation, you can determine the velocity of the objects after the collision.
Compared to the velocity of radio waves the velocity of visible light waves is?
The velocity of visible light waves is the same as the velocity of radio waves in a vacuum, both traveling at the speed of light (approximately 299,792 kilometers per second).
