Luminous objects are objects that generate their own light. Illuminated objects are objects that are capable of reflecting light to our eyes. The sun is an example of a luminous object, while the moon is an illuminated object.
Is the human body luminous or non luminous?
We are pieces of the sun. (we are all like the sun, but very, very faint) That is why we are luminous beings. But our eyes can’t see that luminosity because it is very faint. Our light is too weak, but it is light anyway.
Is a luminous body?
Hint:The luminous body is the body that produces the light on their own. The sun is the natural luminous body and it is the chief source of the light. The light is visible to the human eye by the process of reflection by the objects in the environment.
What considered luminous?
A luminous object is one that produces light. A non-luminous object is one that reflects light.
Which is not a luminous body?
Objects that do not have light of their own but they reflect the light of luminous objects that fall on them to our eyes are known as non-luminous objects. Wood, moon, blue sky, plastics, metals are some of the important examples of non-luminous objects. Earth’s only natural satellite is the Moon.
Which is a natural luminous body?

What is luminous light?
In photometry, luminous energy is the perceived energy of light. This is sometimes called the quantity of light. … Light whose wavelength is well outside the visible spectrum has a luminous energy of zero, regardless of the amount of radiant energy present.
What are the 4 types of luminous light sources?
Natural luminous sources include: Sun. Stars. Fire.
Examples of Luminous Sources
- Lighted candles.
- Headlights on cars.
Why is the earth non luminous?
Why is the Earth a non-luminous object? It does not emit much of it’s own visible light, but it certainly emits light in the infrared from primordial heat left over from the formation of the earth, and the current decay of radioactive elements in the earth.
Can a non luminous body be made luminous?
A non luminous body can be made luminous by heating it.
Which of the following is luminous?
Planets and satellites are non-luminous objects which do not produce light on their own but reflect the light falling so they appear bright in the sky. So according to the question, the sun which is a star is a luminous object while the rest of the options are satellites and planets are all non-luminous objects.
