Is a volcano erupting luminous or non luminous?
It is luminous
Is table luminous or non luminous?
It's non-luminous
Are glow in the dark objects luminous or illuminated?
Luminous.
Is a table non luminous?
Some tables may be painted with luminous paint. Most are not luminous.
Is television luminous or non luminous?
A TV, when it's on and showing an image is luminous. When it's off, it's non luminous.
Name two objects which are non-luminous at room temperature but can be made luminous when heated?
Iron and steel are non-luminous at room temperature, but they can become luminous when heated to high temperatures, such as when they are heated in a forge or during welding.
Is an ordinary frosted incandescent bulb a luminous or an illuminated source?
An ordinary frosted incandescent bulb is a luminous source because it produces light through its own incandescent filament. It does not rely on external light sources to produce light.
Is the temperature of a luminous flame greater ot less than that of a nonluminous flame?
The yellow color in a luminous flame is basically the black-body emission from hot particles of soot in the flame. they are hot, and they glow like the filament of a light bulb. In a blue flame, there are no particles of soot to give that incandescent radiation. Instead, the main color you see is blue emission from the high-energy C2 molecule.
Why should the filament of bulbs be thermally isolated?
Thermally isolating the filament helps to prevent heat loss to the surroundings, ensuring that more of the electrical energy supplied to the bulb is converted to light. This leads to increased efficiency and helps the bulb achieve higher luminous efficacy.
Why are fluorescent lamps brighter than filament light bulbs?
Fluorescent lamps are brighter than filament light bulbs because they produce light by exciting mercury vapor and phosphor coating, which emits more visible light compared to the incandescent process of heating a filament wire to produce light. Additionally, fluorescent lamps are more energy-efficient and have a higher luminous efficacy, meaning they produce more light for the amount of energy consumed compared to filament light bulbs.
Is a volcano erupting luminous or non luminous?
It is luminous
Are light bulbs nonluminous?
Yes, light bulbs themselves are considered nonluminous because they do not produce light on their own. They require electricity to pass through a filament, which then emits light, making the bulb appear luminous.
Is table luminous or non luminous?
It's non-luminous
Are glow in the dark objects luminous or illuminated?
Luminous.
What supports the anther?
The filament supports the anther in a flower.
What means luminous?
Luminous could also mean 'full of light or illuminated'. For example: luminous hands of a clock. Here, luminous denotes shiny or that give light. In the example: luminous room; luminous indicates well-lighted. Something that is clear or easy to understand is also termed luminous. Fro example: luminous prose or luminous theory. Luminous could also mean inspiring, intelligent, or enlightened.
How do you spell luminous?
luminous is correct
