Light+energy

LIGHT ENERGY

The properties of light energy are wavelength and intensity (BRIGHTNESS).

Wavelength is a similar thing to sound. Some have big gaps (LOW PITCH FOR SOUND)between them and some have small gaps (HIGH PITCH FOR SOUND).



Intensity (BRIGHTNESS) is a measure of the energy flux averaged over period of the wave.



REFRACTION: Refraction is the bending of light rays when passing from one transparent material to another.

REFLECTION: Reflection is the light rays being bounced out to opposite side.

THE SPEED OF A LIGHT IN A VACUUM IS APPROXIMATELY 186,282 MILES PER SECOND.

If there is a gravity it is possible to bend light even if travels into a straight line.
