For this question, we are being asked, how does a light given off from your living room lamp differ from a neon lamp? okay, so in other words, we're being asked to compare that two.
00:14
So the main difference is a lamp producing light, does so by heating a metallic filament and this radiates light.
00:23
Whereas neon light produces light by exciting a gas under electrical discharge conditions.
00:30
So, when a neon gas is placed under vacuum with electrodes, as current potential is discharged to the gas in the tube, it forms atoms, ions and electrons and are constantly colliding with each other.
00:46
So many collisions happen such as rapidly, you get a constant buzzing and light emit from this reactions.
00:54
Whereas a lamp, a normal lamp, which you have in your living room, has a constant buzzing and has all frequencies and it will look yellowish also referred to as warm light.
01:04
When we pass light from a prism of all frequencies it will be resolved into the individual colours...
