Why not earth radiate light?
The earth does reflect light, but does not produce light.
Why do we see things?
Because light reflects off objects
What is the best obsevation of refration of light?
The best observation of refraction of light is by observing objects that are in water. By observing objects that are in water, the objects usually appear as if they are not straight.
What are the icy objects that light up the light sky?
comets.
What objects in space emit or reflect light?
sun, stars, galaxies, nebulae, and meteors
What objects can radiate energy?
All objects radiate energy at a rate depending on their temperature.
Why black colour absorb and radiate more heat?
The objects is black when no light reflect from it, hence, it absorb light very well. And at the same time, what can absorb light very well would radiate heat very well .
Do all objects radiate?
no...
Objects that absorbs and radiate heat?
Styrofoam
Do darker objects radiate heat better than lighter objects?
YES
Do dark rocks absorb more heat than light rocks?
Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.
What is a sentence with the word radiate in it?
An incandescent light will radiate at all frequencies.
What is the ability to radiate light?
Luminescence.
Why not earth radiate light?
The earth does reflect light, but does not produce light.
Does all objects in the universe radiate some form of energy?
yes
Do hotter objects radiate more total energy per unit area than colder objects?
Yes
Which method of heat transfer can take place if two objects at different temperatures are placed without touching each other in a vacuum?
Heat doesn't travel through a vacuum. The energy could be changed to light and radiate across the gap, so that would be radiation.
