Does mars reflect or emits light?
Mars does not emit its own light. Rather it reflects sunlight that falls on it.
What is a large celestial body that is composed of gas and emits light-?
A large celestial body that is composed of gas and emits light is called a star.
Does moon in the sky emits light?
No, it reflects the light from the sun onto the Earth.
Which part of the Sun emits UV light?
surface
What sun layer emits visible light?
The Photosphere.
Does a star hold light?
No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.
What object is made black so that it emits heat?
coal is made black so that it emits light
Which throws off more heat a halogen or incandescent flood light?
A halogen light emits more heat than an incandecent light.
Is the light from an incandescent lamp monochromatic?
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
What is earth's external heat engine?
The Earth's external heat engine is the Sun. It constantly emits light, heat, and energy which are absorbed by the Earth.
What is the difference between a LED light bulb and a regular?
a regular light bulb emits about 80% heat energy and only 20% light energy, whereas leds emit about 70 % light and 30% heat
Does a light bulb give off radiant or thermal energy?
THe light bulb emits light while in the process heat in the infrared spectrum is emitted.
Are infrared radiations emitted by glowing of firewood?
Yes - infrared radiation is heat. Glowing firewood emits heat (as well as visible light)
What type of radiation do human bodies give off?
Everything, including the human body, emits heat waves. Not everything emits radiation though.
What is the small spring that is inside a bulb?
This is called the filament. It is what produces light. When voltage is applied it becomes white hot and emits heat and light.
When the ground gets warm it emits an invisible type of light called infrared light. This light can travel into the atmosphere and heat the air that it encounters?
Yes, that is correct.
How does the fact that energy is neither created or destroyed affect an object that emits light?
Well, if the body emits its own light then it first has to make it. So when the light is made not all of the energy put in will become light therefore the energy created will become light, heat and sound (like a light bulb) and so the amount of energy that is wasted on heat and sound will affect the amount of light produced in the long run. Hope this helps
