Group U Luminous Objects

Luminous objects are objects that give out light (Glows or shines).
Things that are not luminous don't give off light but can reflect light example: a piece of glass.
To be able to be luminous the object needs a source of energy.
Examples of luminous objects…
:The sun
:Stars
:Torch (because of the energy from the batteries.)
:Candle

In order for us to see non luminous objects it must reflect some of the light given off by luminous source.Objects that we see on a daily basis such as cars,clouds and the moon are not luminous they just reflect sunlight.
