An atomic spectrum contains a line with a wavelength centered at 442 nm . Careful measurements show the line is really spread out between 441 and 443 nm .
Estimate the lifetime of the excited state that produced this line.

Tried using the ℏ/2 formula, h/4 pi, and set it equal to delta E times delta t.
No luck yet..

Yep that's what I got. I made a dumb error with my scientific notation and that's why I wasn't getting the answer.
