If you want to measure the speed of something, you first have to recall that
speed is (distance traveled) divided by (time to travel the distance), and then
you realize that you have to measure the distance it travels and the time it takes
to travel that distance.
If it happens to be the speed of light, then you immediately have a serious problem.
The speed of light is so great that ...
-- If you pick a distance that's easy to measure, then the time is impossibly short.
For example, if you pick ten miles, then you have to accurately measure 0.00005368
of one second, which is pretty tough.
-- If you pick a time that's easy to measure, then the distance is ridiculously long. For
example, if you pick 0.1 second, then you have to accurately measure 18,628.2 miles,
which is enormously tough.
Both of these methods are theoretically and technically perfect, and completely impossible
to actually use for the speed of light. You have to invent whole new clever ways to measure
speed.
What else can I help you with?
How would you explain the experimental results by adding quantum theory of light?
The quantum theory of light explains the results of experiments by treating light as particles called photons. These photons exhibit wave-particle duality, where they can behave as both particles and waves. This quantum nature of light helps explain phenomena such as interference patterns and the photoelectric effect.
Are decibels used to measure light?
Absolutely. Photographic light meters are designed to measure light for photographic exposure (in a film-speed/shutter-speed/aperture combination), but many hand-held photo light meters can measure light in footcandles, which is a common scale. If you look on places like eBay, you can find inexpensive, digital, brand new meters which read out in Lux or Lumens. Some may read in footcandles as well. It's not difficult to convert from one measure to another (there should be internet calculators which would do it easily).
How do you measure the speed of light?
by getting boners.
1600s Galileo attempted to measure the speed of light using blank?
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.

When was International Centre for Synchrotron-Light for Experimental Science Applications in the Middle East created?
International Centre for Synchrotron-Light for Experimental Science Applications in the Middle East was created in 2002.
Who first proved that light is a wave?
Thomas Young first provided experimental evidence supporting the wave theory of light in the early 19th century with his double-slit experiment. This work laid the foundation for the wave-particle duality of light.
How many attempts did it take Thomas Edison to make the light bulb?
It took him 14 months and in that 14 months it took him 1400 attempts to make the light bulb.
Who invented the light meter?
A light meter is used to measure the amount of ambient and reflected light in photography. This helps to determine the proper exposure for a photograph. A company called Weston marketed the first photographic light meter in 1932.
How does light behave, as a wave or a particle, in different experimental conditions?
In different experimental conditions, light can behave as both a wave and a particle. This phenomenon is known as wave-particle duality. In some experiments, light behaves more like a wave, exhibiting characteristics such as interference and diffraction. In other experiments, light behaves more like a particle, with properties such as momentum and energy quantization. The behavior of light depends on the specific experimental setup and the interactions it undergoes.
What is the experimental procedure of what affects light reflection?
To study what affects light reflection, you would typically set up an experiment where you vary factors such as surface material, angle of incidence, and surface smoothness. You would then measure the amount of light reflected using a light meter or detector. By systematically changing these variables and observing their impact on light reflection, you can identify which factors have the greatest influence on light reflection.
Who try to measure the speed of light?
Roemer was the first to measure the speed of light.
When was By Dawn's Early Light created?
By Dawn's Early Light was created on 1990-05-19.
What has the author Orville Frank Tuttle written?
Orville Frank Tuttle has written: 'Orignin of granite in the light of experimental studies in the system' -- subject(s): Granite 'Origin of granite in the light of experimental studies in the system' -- subject(s): Granite
What is some proof that the moon does not produce light?
A theoretical proof can be easily presented, as there are a small number of reactions that release light, and the conditions for them don't exist on the moon. An experimental proof has probably been presented by now, I doubt you'd need to do much more than measure the light coming from the side of the moon facing away from the Sun.
How can one accurately measure luminescence in a scientific experiment?
To accurately measure luminescence in a scientific experiment, one can use a specialized instrument called a luminometer. This device detects and quantifies the amount of light emitted by luminescent samples, providing precise measurements of luminescence levels. Additionally, proper calibration and control of experimental conditions, such as ambient light and sample preparation, are essential for obtaining accurate results.
Is the wave concept hypothetical?
No. Wave properties of light and electrons are well supported by experimental evidence.
