What is Intensity of Ray? Where to Get Info?

In summary, the conversation revolves around an equation that involves the intensity of a ray and the inability to find information about it. One person suggests that it may be related to irradiance, while another suggests a possible relation to natural line width, mean life time, and Planck's constant. The source of the equation is also questioned.

What is this equation I[tex]\gamma[/tex]=([tex]\Gamma[/tex]N)/D2

It is about Intensity of ray.
But I can't find any information about it.
What is it? And where can I get the information?

I'm not sure, but it looks a bit like irradiance = radiant flux (or radiant power) per area :confused:

see http://en.wikipedia.org/wiki/Radiant_flux"

what book did you get it from?

Hi,
i think it is the relation between natural line width, mean life time and Planck's constant!
the correct relation which i know (FWHM)*meanlifetime=hbar.
 

FAQ: What is Intensity of Ray? Where to Get Info?

What is Intensity of Ray?

The intensity of a ray refers to the amount of energy that is being carried by the ray. It is a measure of the brightness or strength of the ray.

How is the Intensity of Ray measured?

The intensity of ray can be measured using a variety of methods, depending on the type of ray being studied. For example, the intensity of light rays can be measured using a light meter, while the intensity of sound waves can be measured using a decibel meter.

What factors affect the Intensity of Ray?

The intensity of ray can be affected by several factors, such as the distance the ray travels, the medium it travels through, and the properties of the ray itself (such as wavelength or frequency). Other factors may also play a role, depending on the specific type of ray being studied.

Where can I find more information about Intensity of Ray?

There are many resources available for learning more about intensity of ray, including textbooks, scientific journals, and online articles. You can also consult with experts in the field, such as physicists, engineers, or researchers who specialize in studying rays.

How is Intensity of Ray used in scientific research?

The intensity of ray is an important concept in many fields of science, including physics, astronomy, and engineering. It is often used to study and understand the behavior of different types of rays, as well as their effects on various materials and environments. Scientists may also use intensity measurements to make predictions and calculations in their research.
