Light Energy Facts

Light Energy Facts
The potential for light to perform work is called light energy. Light energy is the only form of energy that we can actually see directly. It is formed through chemical, radiation, and mechanical means. Light energy can also be converted into other forms of energy.
Interesting Light Energy Facts:
Light travels at a speed of about 300,000 km/s.
The sunlight that we see here on Earth actually left the Sun 10 minutes before.
During photosynthesis, plants use light energy to create chemical energy.
UV lights are often used by forensic scientists to see details that are not seen by the naked eye.
Although humans cannot see UV light, some insects have the ability to see it.
Optics is the study of light.
The speed of light changes when traveling through different objects.
Light is a type of electromagnetic energy.
Light is made of tiny photons which contain lots of energy.
The intensity of photons is dependent upon the amount of energy they contain.
Space is dark because light is only visible when it has an object of which to bounce off.
Light energy is always moving and can therefore not be stored.
Light is also called electromagnetic radiation when speaking of light other than visible light.
Of all the forms of radiation and light on the electromagnetic spectrum, humans can only visibly see a very small amount of light.
The reason we see different colors of light is because each color has a different wavelength.
