Question

a) List three advantages of fluorescent tubes over filament bulbs.
b) Name three rays that could be used in locating the image formed in a concave mirror and state how they are reflected by the mirror.

Answer 1

Answer:

Fluorescent lamps do not produce as much heat as traditional lighting options. They make about 75% less heat compared to an incandescent bulb because they are not using resistance to emit light. That also results in an energy savings, and also helps to keep whatever room they are in at a cooler temperature.
