Question

How can a 12 W florescent light bulb output the same amount of visible light as a 60 W incandescent bulb?

Select one:

a. Florescent bulbs trap light for five times as long as an incandescent bulb (12 W * 5 s = 60 J and 60 W * 1 s = 60J).

b. Most of the 60 W of electrical energy that go into the incandescent bulb is released as infrared radiation (heat).

c. The incandescent bulb experiences a reaction force which reduces its output by 48 W.

d. The florescent bulb can output 60 W of energy while only using 12 W. It simply creates the other 48 W from nothing.

OPTION .A is ight answer

because when florescent light used in 5 sec and incandescent bulb used at 1 sec same amount of energy is released
