There are different types of energy. In this case, the energy apart from radiant heat is giving off energy in the visible range, ~400-800 nm wavelength. That's why you can see it.
self-luminous.
It's often possible to see non-luminous objects if you illuminate them with a source of light, such as a flashlight, a candle, or a drop of golden sunshine. No object absorbs all of the light that falls on it, so some light is always reflected from it, and some of that reflected light finds its way to your eye. Once any of the light falling on the object has reflected from it, it's very much as if the object were self-luminous.
i think luminous means when something gives off light and non-luminous means when something does not give off light.
An object that cannot make its own light is called non-luminous. Non-luminous objects do not emit light on their own but can be seen when illuminated by a light source.
The color of the candle wax does not affect the rate at which the candle burns. The main factors that determine how fast a candle burns include the size of the wick, the quality of the wax, and the environment in which the candle is burning.
yes
A candle flame is seen because it consists of glowing gases.
It is bright, and could not be seen clearly as it emits light
A candle flame is seen because the carbon hydrogen bonds in paraffin are being broken and energy is released as photons. The photons activate the photoreceptors in your retina to form an "image", then that image travels to the back of the brain through the optic nerve to be interpreted. The carbon and hydrogen atoms form new bonds with oxygen with their electrons in a lower energy state(as carbon dioxide and water).
luminous flames are those which throw or Emmit bright light of great intensity......but non luminous flames are those which just glow and do not emmit light of such great intensity................ it should not be misunderstood with candle ......and coal........as one emits flame and the other does knot's as there is no flame......there is no point of luminous or non luminous
when a candle is lighted ; this is what happens : the solid wax melts and rises up the wick. The wax vapours react with oxygen to burn as a flame. The candle starts melting. This is a physical change. while observing the candle flame we see that the candle has 3 zones. Non - Luminous zone is the innermost zone. It appears as a dark zone and is the coldest part of the candle flame due to less oxygen. Then comes the Luminous zone , it is yellow and opaque. The glowing of carbon particles cause the flame to look yellow and emit light. Then , Invisible zone - it is the outermost zone of the candle flame. it is the hottest zone and cannot be seen with naked eye. Combustion reaction comes to completion here and carbon changes into carbon dioxide.
The flame on a candle is often seen as a symbol of life, light, hope, and purity. It can also represent warmth, guidance, and spiritual illumination. Additionally, in some cultures, the flame is believed to symbolize change and transformation.
Non- Luminous can burn efficiently 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. Hotter flames burn blue and (relatively) cooler ones burn yellow.
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.
Its Flame Test:it gives golden yellow colour to non luminous flame which is not seen through a blue glass.
self-luminous.
A candle can typically be seen from up to 1 mile away in the dark, depending on atmospheric conditions and line of sight. The flame emits light that can be visible in the surrounding darkness, but this visibility diminishes with distance.
