what are the wavelengths that plants need to produce energy?

"Red and blue". It's a bit more complicated that that though;
the two primary photosynthetic pigments are chlorophyl A
and B. THeir absobtion peaks are at 430nm,662nm and 453nm,642nm
respectively.

But there are other photosynthetic pigments, that is the
range of light that results in photosynthesis does not
exactly match the absobrtion spectra of chlorophyll.

Caratinoids, whihc are red, orange and yellow in color
have their maximum absobrtion bewteen 460nm and 550nm.

do they need uv-a and uv-b light or is normal light enough?

UV stunts plant growth.
