In vacuum . . . 299,792,458 meters (186,282 miles) per second.
In material substances . . . somewhat slower, depending on the substance.
What else can I help you with?
What kind of measurement of the speed of light would you consider a direct measurement?
A direct measurement of the speed of light would involve measuring the time it takes for light to travel a known distance, such as using a laser and a precise timing device.
What is EMCsquare?
the measurement of energy mass speed of light
What is the exact speed measurement of light?
The speed of light in vacuum is 299,792,458 meters (186,282 miles) per second.
An indirect measurement of the speed of molecules is made with a?
An indirect measurement of the speed of molecules can be made using techniques such as Doppler spectroscopy or light scattering. These methods analyze the behavior of light as it interacts with the molecules to determine their speed indirectly. By studying the changes in the properties of the light, scientists can infer the motion and speed of the molecules.
The speed of light is what in space?
The speed of light in a vacuum (space) is about 3x10^8 m/s. The most accurate measurement is:
How did physicist calculated the prise measurement of the speed of light?
Stop watch and a light switch
What is the SI measurement of light?
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
What is the measurement for the speed at which an electrical current can do work is?
electricity travels at the speed of light +186,000 miles per second
What is a measurement of distance based on the speed of light?
A unit that is commonly used in astronomy is the light-year - the distance light travels in a year.
What is the uncertainty in the measurement for the speed of light?
The uncertainty in the measurement of the speed of light is typically around ±0.3 meters per second. This uncertainty arises from various factors such as experimental errors, instrumental limitations, and environmental conditions. Multiple measurements and techniques are used to reduce this uncertainty and obtain a more accurate value for the speed of light.
How is the refractive index measured and what methods are commonly used for this measurement?
The refractive index is measured by comparing the speed of light in a vacuum to its speed in a material. Common methods for this measurement include using a refractometer, spectrometer, or interferometer.
Who found the speed of light?
An early measurement was done by Ole Rømer, by observing Jupiter's moons.
