6PH02:HOW WAS PHYSICS UNIT 2?
Saladin:
For the light it is a different thing.
You see when the light rays hit, they go into antiphase.
This causes them to super impose with the light outside.
Thus, this causes areas of darkness and areas of light.

For the UPS, the thing is that the computer is not 100% efficient.
So, that means that more of the power is used, compared to 700W, from which 80% may be used, to 350 W, from which 80% is to be used.
The 350 has less power wastage. Thus, meaning that more of the power is actually used in comparison. So it is not really completely halved.
