the last one now, I figured the other ones out.

(conversion: 1 angstrom = .1nm = 1e-10)
Wavelengths in angstroms:

Red: 6682
Blue: 4470

give the frequency of the red(in sec^-1)
give the energy of the blue(in J)

**Thanks in advance!!

I got an extension, so if anyone knows how to work the problems, help would be great.
