solar oven

[heier]

I am doing a project on a parabolic (umbrella) solar oven. I was posed a question which i am not sure what they r asking. The question is:

Describe how the umbrella solar oven uses short wave and long wave radiation. Please help.

Do you understand the concept of different wavelengths in the electromagnetic spectrum? If not, you need to do some reading on the subject. What range of wavelengths did you design your solar umbrella reflector to handle? Once you know the wavelengths that you designed for, answering

Describe how the umbrella solar oven uses short wave and long wave radiation.

becomes a matter of describing how the shortest and longest wavelengths you designed for are handled by your design.
