How is the human body's luminosity compared to a 60 watt light bulb?

Very low (virtually none) even though we use a little more power than that.
(Different design.)

Total light output of an object is called?
Luminosity
Si unit for light intensity?
Light intensity is also known as luminosity. Candela is the si unit
Is aluminum light or heavy?
Compared to Osmium it is light, compared to Hydrogen it is heavy
Yellow light compared to orange light?
different colors
What is darkness compared to light?
its darker
The amount of light a star gives off is called what?
its called magnitude or luminosity. :) hope it helped you.
Total light output of an object is called?
Luminosity
What is the luminosity of the night sky. How much light do the stars produce relative to us compared to the sun?
The luminosity of stars varies quite a bit. Most stars (about 85-90% of them) emit less light than our Sun, while a few very massive stars emit, in extreme cases, over a million times as much light (or more precisely: total radiation) than our Sun.
What is another word for light that starts with l?
luminosity? maybe?
What is the root word of luminosity?
The root word of "luminosity" is "lumin," which comes from the Latin word "lumen" meaning light.
What luminosity measure that different from what absolute visual magnitude measures?
1.Luminosity is the amount of light emitted from a certain light source whereas brightness is the amount of light manifested or received. 2.The area of illumination is inversely proportional to brightness whereas luminosity isn't. 3.Brightness is usually expressed in 'Lumens' whereas luminosity is expressed in candela per square meter (photometry).
How do astronomers measure stellar luminosity?
The reference that astronomers use to compare the luminosity of other stars is the sun's luminosity. The luminosity is denoted in multiples of the sun's luminosity. For example, the luminosity of the star Sirius is 25 times the luminosity of the sun.
What percentage of energy does an energy saving bulb save compared to an ordinary bulb?
It varies, depending on the specific model, but an energy-saving (fluorescent) light bulb should save at least half the energy, for the same luminosity, compared to the old-fashioned incandescent light bulbs. The incandescent light bulbs ought to be outlawed, except for specific purposes where the heat they generate is actually needed.
Si unit for light intensity?
Light intensity is also known as luminosity. Candela is the si unit
What is luminosity and how does it relate to your study of the solar system?
Luminosity is brightness and is a measure of how much light a star is giving out.In astronomy absolute magnitude is a measure of a celestial object's intrinsic brightness.Obviously the further away an object is the dimmer it will appear to be, so that when comparing the brightness of one star with another, all stars are moved to a theoretical distance of 10 parsecs (about 32.616 light years, or 3 × 1014 kilometres) and their brightness compared one with another.One can compute the absolute magnitude 'M' of an object given its apparent magnitude 'm' and luminosity distance 'DL':M=m-5((log 10DL)-1)where 'DL' is the star's luminosity distance in parsecs, wherein 1 parsec is approximately 3.2616 light-years.
What is luminosity in art and design?
The brightness of the pixel within the image on a scale of 0 to 255
What is the difference between light rays and heat radation?
Light rays are visible and have higher frequency compared to that of heat radiation Heat radiation is nothing but infra red which is not visible to human eyes. They have longer wavelength compared to that of visible light
