What else can I help you with?
What is one example of where energy transfer by radiation is occurring?
A good example is the energy we receive from the Sun. We receive this energy mainly as electromagnetic radiation, such as visible light and infrared.
What are the two kinds of light energy?
The two kinds of light energy are visible light and invisible light. Visible light is the portion of the electromagnetic spectrum that is visible to the human eye, while invisible light includes ultraviolet, infrared, and other forms of light that are not visible to the naked eye.
Is an infrared led visible to the naked eye?
The LED itself is visible, the light it emits is not. You can "see" the light by looking at it through a camera, for example the one on your cellphone!
Why can radio telescope can see things that a telescope that detect visible light cant?
-- The source may be one that emits electromagnetic energy in the radio portion of the spectrum but little or no visible light. -- There may be material in the way, such as dust or gas, that absorbs visible light but doesn't absorb radio energy.
One example of an energy effecient device is an?
An example of an energy efficient device includes an energy efficient light bulb.
When the electrons release energy as visible light where do the electrons go?
Yes. When electrons go from a higher energy orbital to a lower one, they release photons (ie: light).
Give an example of one type of energy conversion?
Mechanical energy is supplied to a generator from an engine, a steam turbine for example, and converted to electrical energy
How do you know energy when you see it?
Energy itself is not visible, but its effects can be observed. For example, if you see something moving or light being emitted, you are witnessing energy in action. Energy can take many forms, such as kinetic, potential, thermal, and electromagnetic, and it can be transferred or transformed from one form to another.
Why is a light bulb a example of light energy?
A light bulb is an example of light energy because it transforms electrical energy into light energy. When the light bulb is turned on, electrical energy flows through the bulb, causing the filament to heat up and produce light. This process demonstrates the conversion of one form of energy (electricity) into another form (light).
Which has higher frequencies microwaves or visible lights?
Visible light has shorter wavelengths than microwaves. Microwaves, which might be considered the highest energy radio waves, have a longer wavelength (and a lower frequency) than visible light.
What is one difference between visible and non-visible light?
One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.
Does fire emit infrared light?
Yes, fire emits a combination of visible light, infrared radiation, and heat energy. Infrared light is one component of the electromagnetic spectrum emitted by fire, along with visible light and ultraviolet radiation.
