Question

one can perceive the 100- Hz flicker in a fluorescent tube light ( by moving / sweeping our eyes swifly across the tube light), but any such flicker is not perceived in a incandescent bulb. Explain why?
​

Answer 1

Due to the high ignition temperature, we observe a flicker in the fluorescent bulb.

Explanation:

• It is because the electrodes in fluorescent bulbs are highly ignited by the intense temperature that is why we see a flicker.
• The electrons move at a very rapid rate from one place to another to show a little spark.
• While in an incandescent bulb, the current is a normal alternating current and the heat is cooled at a very low rate that our eye can not detect a flicker in it.
