Question

What is normally used in solar cookers to concentrate the sunlight​

Answer 1

Explanation:

A solar cooker lets the UV light rays in and then converts them to longer infrared light rays that cannot escape. Infrared radiation has the right energy to make the water, fat and protein molecules in food vibrate vigorously and heat up.

Answer 2

Box Cookers – Box solar cookers have transparent tops made of either plastic or glass and can have added reflectors to help concentrate the sunlight. Box cooker tops can generally be taken off to allow containers of food to be placed inside.
