First of all, this was a bit garbled up, so it is sort of incomplete. 

You gave me a total of 43 words, and I only counted 41 slots on the crossword graph itself, which is problematic. 

I got as far as I could, but some of the words either weren't provided, or the spaces were made incorrectly for the length of these words.

2. (black / pitch) 
7. conservation 
9. radiation 
12. crest 
13 ? 
14. <em>whatever you wrote</em> 
15. dense

31. (pitch / black) 
34. voltage 
35. insulator 
38. amplitudes
