Is Diamond a luminous object?
A diamond isn’t luminous object. It doesn’t have light of it’s own. Although it is a great thing to reflect the light that falls on it. That purity is what allows the diamond to show the dispersion of light and that’s the beauty.
Is Earth a luminous body?
It is known that the earth does not emit any light of its own. So it is non- non-luminous body.
Is Mars is a luminous body?
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.
Is Sun a luminous body?
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. Without light, there would be no sight.
Which is not a luminous body?
Moon is not a luminous body because it does not emit light of its own. Moon reflects the light of the Sun, hence it appears shining.
Is a TV luminous?
An object which gives out its own light is called a luminous object. For example, Sun, stars, burning candles, electric bulbs, glowing tube light, television screen, a piece of red hot iron, a flame of a gas burner, and fireflies are all luminous objects.
What is luminous?
1a : emitting or reflecting usually steady, suffused, or glowing light luminous objects—the nebula, the stars, the planets— Lincoln La Paz. b : of or relating to light or to luminous flux. 2 : bathed in or exposed to steady light luminous with sunlight.
Is a mirror luminous?
Mirror is not a luminous object since it does not emit its own light but reflects and absorbs light rays coming from the sun .
How do we see non luminous object?
Non-luminous objects reflect the light falling on them and the reflected light are sensed by the eye and thus we are able to see non-luminous objects.
Is a light bulb luminous or non luminous?
Objects that emit light on their own are called luminous objects. Best examples of luminous objects are the sun, stars, light bulb etc. Objects that do not reflect light are known as non luminous objects.
What are the 4 types of luminous light sources?

- Lighted candles.
- Lamps.
- Headlights on cars.
- Flashlights.
Is wood a non luminous object?
Objects like the moon that do not give out or emit light of their own are Non- luminous objects. Moon is an example of a non-luminous object as we can see the moon because it reflects light from the sun. Other examples of Non luminous bodies are pen, pencil, chair, wood etc.

What are the 2 types of flames?
What are the two essential types of Flames ?
- Non-luminous or blue flame.
- Luminous flame.
Why are non luminous flames blue?
Because luminous flames don’t burn as efficiently as non-luminous ones, they don’t produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue.
What is luminous zone?
Middle zone: The middle zone also known as luminous zone is the zone which is moderately hot with limited oxygen supply. Hence, the fuel vapours burn partially and produce carbon particles. These particles then leave the flame as smoke and soot. This zone is the major part of the flame.
What is the Colour of luminous zone?

Which zone is hotter than luminous zone?
The non-luminous zone is hotter than the luminous zone and is the hottest zone.
