Lightbulbs do get hot when lit - even cfl bulbs get a bit hot.
Chemical to radiant(light:)
Yes,it provides red and blue light.
When a bulb is lighted up, electrical energy is converted into light energy and heat energy. The electrical energy flows through the filament in the bulb, causing it to glow and emit light while also generating heat.
Cause from the heat coming off the light bulb.
On lighted vanity mirrors you want to use a vanity mirror light bulb. The bulb is very round where the light is produced and is not very long.
The bulb "pulses" because the circuit is not completely off. If the CF bulb is pulsing or flashing, it means that there is some kind of feedback loop providing at least some voltage to the bulb. Often lighted switches use the filament resistance to provide voltage to the internal bulb. Get rid of the lighted switch.
if the one bulb is not lighted the all is no lighted
This is because the tail light bulb has a different element in the bulb. Just replace the bulb and that will fix the problem.
You would place the convex lens between the lighted bulb and the screen, with the lighted bulb positioned beyond the lens's focal length. This arrangement will create an enlarged image of the lighted bulb on the screen due to the converging properties of the convex lens.
The flashlight lighted up because there is a source of electricity, typically provided by batteries, that powers the bulb to emit light when the switch is turned on.
Yes, because you are only removing that one lightbulb from the circuit.
Stars give out light energy, that is they are luminous. Thus we see them for the same reason we see a lighted torch bulb.
