Two examples of self luminous?
The sun is a self-luminous celestial body that emits its own light and heat through nuclear fusion reactions in its core. Fireflies are insects that are self-luminous due to a chemical reaction in their bodies that produces light, often used as a signal for communication and mating.
Definition of luminous and non-luminous sources of light?
Luminous sources of light are objects that emit light due to their own energy, like the sun or a light bulb. Non-luminous sources of light are objects that reflect light from luminous sources without emitting light themselves, like the moon or a mirror.
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 a glow in the dark ball luminous or illuminated?
A glow in the dark ball is considered luminescent because it emits light through a chemical reaction or energy absorption rather than being illuminated by an external light 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 is a luminous light source?
Luminous light is a light source but another name for it.
Distinguish between a luminous source and an illuminated source?
A luminous source produces its own light, like the sun or a light bulb. An illuminated source does not produce light but reflects light from a luminous source, such as the moon reflecting sunlight.
What does luminous object contain?
A luminous object contains its own source of light, such as the sun, a light bulb, or a candle. These objects emit light energy that allows them to be seen in the dark.
What is non luminous source?
It is a source which does not produce light.
What is a self-luminous object?
A self-luminous object is an object that emits its own light or electromagnetic radiation, such as the sun, stars, or lightbulbs. Unlike reflective objects that only reflect light from other sources, self-luminous objects generate their own illumination.
What is a hot self-luminous shpere of gas?
star

Is a flashlight luminous or illuminated?
A flashlight is considered illuminated because it emits light due to an internal power source (battery). Luminous objects generate their own light without requiring an external source.
Which is the first self-luminous planet in solar system?
Neptune
What are Objects that create light are said to be?
Self-luminous objects.
What is luminous source?
A body that can give off electromagnetic radiation (light) such as the Sun, a lightbulb, etc.
How is a star different to a planet?
'cause the star is self luminous and the planet is not .
