Group G Luminous Objects

objects which emit there own heat and light are called luminous objects

example: light bulb
bunsenburner
stove
sun
starsmonitor
TV
etc…

And non luminous objects are

Earth, bricks, plastic, metals, moon, planets
and mirrors!

The reason this is is because they do not make their own light. Light from other sources reflects off these objects so that we can see them.
