Describe an application where a parallel circuit might work better than a series circuit

In rooms where there are multiple lights, a parallel circuit is better.

In a series circuit, if one light broke, all of the lights would turn off, as the circuit would be broken.

However, in parallel, if one bulb broke, the circuit could still be complete through the other bulbs, so they will stay on.

An electromagnetic wave is a wave of energy with a frequency within the electromagnetic spectrum

I got this from a dictionary hope this helps :)
