Four. Lighting (light) light is electromagnetic radiation with frequencies estimated from Hz to Hz or a wavelength in the range 400 to 700 nm, the human eye is very sensitive to the electromagnetic waves. Objects with very high temperature .
4. the light (light) light is an electromagnetic frequency estimated from Hertz, Hz, or a wavelength in the range 400 to 700 nm. The human retina sensitive electromagnetic this range. Very high temperature object
4.The light (light) light as electromagnetic waves that have a frequency by approximately from Hz to Hz or a wavelength in the range 400 to 700 NM retina detachment of human sensitivity to electromagnetic fields at the moment the object that is very very very high temperature
