Definition of luminous and non-luminous sources of light?
what is luminous, non luminous and illuminous source of light.
Is a glow in the dark ball luminous or illuminated?
It is a source of light, hence luminous.
What is the difference between a lumen and a candela?
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', while luminous flux is similar to the rate at which light leaves its source.
Are satellites luminous or non-luminous?
Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.
Which luminous light source in the solar system did the light bouncing off Jupiter's moon come from?
the sun
What is a luminous light source?
Luminous light is a light source but another name for it.

What is non luminous source?
It is a source which does not produce light.
Is a glow in the dark ball luminous or illuminated?

What is a hot self-luminous shpere of gas?
star
Which is the first self-luminous planet in solar system?
Neptune
What does luminous object contain?
Self-illuminating would be phosphorous.
How is a star different to a planet?
'cause the star is self luminous and the planet is not .
What is lumens per watt could you give a brief definition about lumens per watt?
Luminous efficacy is a figure of merit for light sources. It is the ratio of luminous flux (in lumens) to power (usually measured in watts). As most commonly used, it is the ratio of luminous flux emitted from a light source to the electric power consumed by the source, and thus describes how well the source provides visible light from a given amount of electricity.This is also referred to as luminous efficacy of a source.
What are non-luminous source of light?
light which do not give out their own light
What is the difference between a lumen and a candela?
The candela measures luminous intensity, whereas the lumen measures luminous flux. In simple terms, you can think of luminous intensity as being similar to 'brightness', while luminous flux is similar to the rate at which light leaves its source.
What element is used in self-luminous paint?
In modern times, Cobalt-60 is the substance used to make self-luminous paint. Cobalt-60 has replaced Radium's use for the same applications due to Radium's radiation danger.
