What determines whether an object is a net emitter or a net absorber of radiant energy?
Whether an object is a net emitter or net absorber of radiant energy depends on its temperature compared to its surroundings. Objects at a higher temperature than their surroundings emit more energy than they absorb, making them net emitters. Conversely, objects at a lower temperature than their surroundings absorb more energy than they emit, making them net absorbers.
Is a good absorber of radiation a good emitter or a poor emitter?
Well, honey, let me break it down for you. A good absorber of radiation is also a good emitter. It's like a give and take relationship - what goes in, must come out. So, if something sucks up radiation like a sponge, you can bet your bottom dollar it's gonna spit it back out just as well.
If you know that a surface is a good absorber of energy what can you infer about its ability to radiate energy?
If a surface is a good absorber of energy, according to Kirchhoff's law of thermal radiation, it must also be a good emitter of energy. This is known as the principle of reciprocity. Therefore, if a surface can absorb energy efficiently, it will also radiate energy effectively. This relationship is crucial in understanding the behavior of objects in thermal equilibrium.
Why does a good absorber of radiant energy appear black?
In short, because they "don't reflect'." A matte surface isn't smooth; it has a surface that does not fully reflect light/radiation; the surface looks dull because there's little reflection. A smooth surface will reflect because it's smooth (glass-like) and will reflect or bounce light away from its surface. The surface looks shiny because of the reflection. The color of the surface matters because the darker the color, the more light/radiation is absorbed. Lighter colors reflect light; darker colors absorb light.
How do you use radiant energy in a sentence?
Solar panels convert radiant energy from the sun into electricity.

Conversely, objects at a lower temperature than their surroundings absorb more energy than they emit, making them net absorbers.
What determines whether an object is a net absorber or a net emitter of radiant energy at a given time?
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.
Is the pupil of your eye an emitter of radiant energy or an absorber of radiant energy?
The pupil does not absorb anything, it transmits light energy to the retina at the back of they eye, the retina does the absorbing. It certainly does not emit anything either, though aliens in scifi films can have glowing eyes! Some animals like cats have reflective eyes, but they are not emitting light, only reflecting incident light.

Is light kinetic or potential energy?
good answer but its none of them light energy is radiant energy

Does radiant energy come from the sun?
Yes, the sun is a source of radiant energy. The light the sun produces is radiant energy.
What is the energy carried by an electromagnetic wave is called?
Radiant Energy
What causes radiant energy?
Radiant energy is defined as the energy of electromagnetic radiation. This means that radiant energy is caused by the oscillation of electric and magnetic fields.
How do you use radiant energy in a sentence?
Solar panels convert radiant energy from the sun into electricity.
