Why a luminous flame is not used as a source of heat in a laboratory experiment?
Because it makes the apparatus black when heating
What is luminous color?
Luminous colours are bright and kind of glow in the dark like a hivise and these are the luminous colours: luminous pink Green Yellow Blue Orange
Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light. The sun is luminous; the moon is non-luminous.
how can a flashlight be both luminous and non-luminous at the some time?
A flashlight is luminous when it emits light (turned on). It's non-luminous when it's off or the battery dies.
What are the similarities of luminous and non-luminous?
They both produce heat
What is a luminous light source?
Luminous light is a light source but another name for it.
Definition of luminous and non-luminous sources of light?
what is luminous, non luminous and illuminous source of light.
What is non luminous source?
It is a source which does not produce light.
Is a glow in the dark ball luminous or illuminated?
It is a source of light, hence luminous.
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.
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.
What does a spectograph tell us?
A spectrograph tells us which colors (wavelengths of light) are in a luminous source.
What are some luminous sources of light in the solar system?
The only source of light in the solar system is the Sun.
Why a luminous flame is not used as a source of heat in a laboratory experiment?
Because it makes the apparatus black when heating
Which luminous light source in the solar system did the light bouncing off Jupiter's moon come from?
the sun
