Want this question answered?
Thomas Edison is quoted as saying "I did not fail, I found 2000 ways how to not make a light bulb." He did finally succeed in finding the one way to make a light bulb.
If you meant to say WHEN was the light bulb invented, it was invented October 22, 1879.
They refract.When light passes from one transparent medium to another then the light ray refract or we can say it deviate from its straight path.
Bright idea
Depends on your definition of waste. The obvious one is heat unless you are using bulb for an Easy Bake oven in which case the light might be considered waste and heat the primary usage. One could also say that in certain bulbs perhaps there are some light frequencies that may be annoying or not useful.
Ampoule - light bulb.
It is extremely coherent and focussed, not scattered like, say a light bulb.

Light bulbs provides light with the help of electricty,so we can say that bulb consume power and unit of power is watt.one kilowwatthour is equal to one unit also.

You know..you're really not that bright. - Elizabeth Leffingwell
i would say no because the battery has a lot of energy to pass to the light bulb and not a pataoe
A: HARD TO SAY because a bulb has different resistance as it warms up
! It depends on how fast you want them to do it. but I would say 2 squirrels
No. One is chemical energy, the other is electrical energy.

Albert Einstein did not invent the light bulb.
