Which naval officer did experiment on speed of light?
The naval officer who conducted experiments on the speed of light was Albert A. Michelson. He was a U.S. Navy officer and physicist known for his precision measurements of the speed of light, leading to significant advancements in the field of optics. Michelson's experiments culminated in the Michelson-Morley experiment, which aimed to detect the presence of the "luminiferous ether" and ultimately contributed to the development of Einstein's theory of relativity. He was awarded the Nobel Prize in Physics in 1907 for his work.
Who discovered lightspeed?
The theory that nothing can travel faster than the speed of light in a vacuum was first proposed by the famous physicist Albert Einstein in his Theory of Relativity in 1905. The concept of the speed of light being constant and a universal speed limit has since been confirmed through various experiments and observations.
What percentage of the speed of light in vacuum is the speed of light in water?
When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.
Is there proof that the speed of light is not the speed limit?
The speed of light is only the speed limit for information. There are many experiments showing that we can made "non-information" travel faster than the speed of light. For example, in quantum mechanics the phase velocity is faster than the speed of light but the group velocity is slower (or equal to) the speed of light. Also, if two light waves are traveling at the speed of light and they interact, e.g. they constructively interfere with each other, the interference can travel faster than the speed of light. Once again, the speed limit of light is only on information. The word "information" is sometimes tricky to define though.
Speed of light will be minimum when it passes through?
The speed of light is constant and does not change based on the material it passes through. However, when light enters a medium such as glass or water, its speed decreases due to interactions with the atoms in the material.
What kind of experiment can be done for light?
You can do many, many experiments with the light. I'll just mention few categories:- Reflection of the light - Refraction of the light - Spectrum related experiments - Experiments that prove the wave nature of the light (interference) - Experiments that prove the particle nature of the light - Experiments that measure the speed of the light in space - if small scale, usually using interference etc... You may search on internet for specific experiments, by using the words of the categories mentioned upper, to narrow your search results.

How do know how fast light travels?
Its speed has been measured accurately, using lasers.
Which naval officer exemplified the new Navy's drive for professional development and leadership in naval sciences with his experiments on the speed of light?
Admiral Hyman G. Rickover is the naval officer who exemplified the new Navy's emphasis on professional development and leadership in naval sciences through his experiments on the speed of light. His groundbreaking work in nuclear propulsion and his push for innovation and efficiency in the Navy had a lasting impact on naval technology and strategy.
How does light travel through emty space?
Light travels through empty space as electromagnetic waves, with no need for a medium to propagate. These waves consist of oscillating electric and magnetic fields that can travel across the vacuum of space at the speed of light. This is a fundamental property of light and is one of the key principles of modern physics.

When light with wavelength of 589 nanometers moves through water at the temperature of 20° C, its speed is 75% of the speed of light in vacuum.

How does sunlight from the sun get to the earth?
Light is an electromagnetic wave, composed of fluctuating electric and magnetic fields, and these fields do not need the presence of any physical medium to support propagation. Before this was realised, people proposed that there must be some medium, given the name "the ether" to support the light. It was attempts to discover the speed of the earth through this "ether" which led ultimately to the theory of relativity and modern physics.
What was Michelson-Morley Experiment?
The Michelson-Morley experiment was performed in 1887 by Albert Michelson and Edward Morley at what is now Case Western Reserve University. It is generally considered to be the first strong evidence against the theory of a luminiferous aether. The experiment has also been referred to as "the kicking-off point for the theoretical aspects of the Second Scientific Revolution."[1] Primarily for this work, Albert Michelson was awarded the Nobel Prize in Physics in 1907. == ==

Why speed of light is greater than speed of sound?
The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.
What was albert michelson experiment?
Known as the Michelson and Morley experiment, this was an experiment to measure changes in the speed of light. Supposedly, as Earth travelled through the Ether, light would go faster in one direction than in the other (because of the relative velocities). The experiment didn't produce the expected result - the speed of light was found to be always the same. Today, this is an accepted fact - that the speed of light is the same for all observers - and is one of the bases for the Theory of Relativity.
