Is table luminous or non luminous?
It's non-luminous
Is a table non luminous?
Some tables may be painted with luminous paint. Most are not luminous.
What is an example of indirect light?
Where light has bounced off a surface first, rather than coming direct from the source. For example, light coming from an object on a table such as an apple. There is no light in the apple, but light comes off it from a bulb or the sun.
How high to you hang a light over a table?
The specific height of a light above a table depends on the purpose of the table. It is recommended that a light be about 30 inches above a dining room table and about 18 inches above a gaming or work table.
What objects give light in the home?
Lamps of various kinds (ceiling lamps, standard lamps, desk lamps, table lamps, etc.); also, candles, torches, TV and (most) computer screens, LEDs (Light Emitting Diodes; e.g. the power light on a TV or computer), and anything that gets hot enough to glow, so the heating elements of electric cookers and ovens and some electric heaters also fit into this category. You could include luminous objects like the luminous (sometimes radioactive) paint on the hands of some analogue clocks. Oh, and of course the Sun as well - it probably provides drastically more light than any other source in most homes. I guess other stars also contribute, but not so much that you'd notice. Although whether these celestial objects even count as answers to your question depends on exactly what you mean by 'give light in the home.' I can't think of any others. Hope this helps :)

The surface of the table needs to be able to resist cuts, so it must be made from a durable material. A strong light source is another requirement. Having a place to organize all of the tools and implements is a nice thing to have on such a table.
