The Moon gets its light from the Sun. In the same way that the Sun illuminates Earth, the Moon reflects the Sun’s light, making it appear bright in our sky. Is the side of the Moon facing the Sun always illuminated? Yes, just like the side of Earth facing the Sun always is illuminated.

In order for us to see an object that is non-luminous, it must reflect some of the light it receives from a luminous source, such as the Sun. Most of the objects we see, such as cars, clouds or even the Moon, are not luminous; it is just that they reflect sunlight.

Moon is not a luminous object, rather it is a non luminous object. ☆ What are luminous objects? Luminous objects are the objects which emit their own light energy. They cause the sensation of light, therefore they are seen on their own.

Moon reflects the light of sun and not its own light. So, moon is a non-luminous body.

It is known that the earth does not emit any light of its own. So it is non- non-luminous body.

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.

Diamonds get their brilliance from three things: reflection, refraction and dispersion. Reflection is the light that hits the diamond and is immediately bounced back up, giving it an instantaneous shine. Only a portion of the light hitting a diamond is reflected; the rest travels through it.

Mirror is not a luminous object since it does not emit its own light but reflects and absorbs light rays coming from the sun .

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.

Answer. Firefly is neither luminous nor non-luminous because it emits light because of chemical activities at the back of body…

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. 3 : clear, enlightening a luminous explanation.

Luminous objects:- The objects that can emit light energy by themselves are known as luminous objects. Objects like the sun that give out or emit light of their own are luminous objects. Other examples of luminous bodies are Electric bulb, torch etc.

Answer: Opaque materials are those objects which does not allow light to pass through them. Example: – Wooden board, umbrella. Luminous objects are those which emit light on their own.

Difference Between Luminous and Non Luminous Objects

NO, it is not a Luminous object because it does not produce energy by itself. It needs power to produce energy.

Non-luminous objects are the objects that do not have their own source of light energy and hence they cannot emit light and are not responsible for vision. These objects can only be visible due to luminous objects. Examples of non-luminous objects are the moon, plants, and spoons.

An object which gives out its own light is called luminous object. For example: Sun, stars, burning candles, electric bulb, glowing tube light, television screen, a piece of red hot iron, flame of gas burner, firefly are all luminous objects.

We know that luminous objects can emit light energy from their own body. They are visible by their own lights. Similarly, non-luminous objects cannot emit light energies so that they cannot be visible by their own. They are visible by the emitted light energy by the luminous bodies.

Answer: All objects which emit light energy by themselves are called luminous objects. The reason is that moon does not produce its own light. Instead, it reflects the light of the sun falling on it.

Non-luminous objects do not emit their own light, but may shine by reflecting light falling on them.

Luminous flame is bright yellow in color. Non-luminous flame is light blue in color. Flames are sooty (produces soot). Flames are not sooty (Does Not produces soot).

I learnt that there are two different types of flame: the non-luminous flame and the luminous flame. The luminous flame will turn into a non-luminous flame when the air-hole is opened. A luminous flame is orange in colour which can be clearly seen. Surprisingly, it is not very hot.

Luminous flame is formed when the airhole is closed thus the gas will only mix with surrounding air at the point of combustion at the top of the burner and is yellow due to an incomplete reaction.

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.

yellow colour

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

blue

Difference between Luminous and Non-Luminous Objects

The outermost zone is the hottest among all zones and is blue in color, and this is due to complete combustion. The middle zone of the candle flame is moderately hot and is yellow in color, and partial combustion of fuel takes place. It is bright part of the fire.

The innermost zone, directly above the wick, contain wax that has been vaporized but that is unburnt. It is the darkest zone. The middle zone is yellow and luminous because As it is an oxygen-depleted zone, insufficient oxygen exists to burn all of the wax vapor. As such, partial combustion of wax takes place.
