The amplitude of the electromagnetic waves coming from

a light bulb is exactly an indication of the energy carried by

the waves.

If their amplitude decreases, then the waves are carrying less

energy. The brightness of the light decreases, AND the bulb

runs cooler, because it produces less heat.
