Question

which of the following is used in a solar cooker to harvest the Solar Energy first solar panel second Silicon sale third mirror four glass lid

Answer 1

The correct answer is third i.e, mirror.

Specifically mirror are used here. In a mirror, specifically concave mirror, the solar rays comes from infinity and they are made to converge in the concave surface of the mirror and focussed. So all the sun's rays get concentrate at a particular point. This is how it works. So mirror are used to harvest solar energy.

Answer 2

It seems the third option that is mirror is appropriate in this context.

Solar cooker uses sunlight for cooking purposes. The solar panels convert solar energy to heat energy using the silicon cells that are there in the mirror.
