Asked by Nicole

what is the energy of a 606 nm photon emitted from a light source?
Answer in units of J.
Answered by DrBob222
E = hc/wavelength
606 nm must be converted to meters.

i did that. but the answer was wrong.
i got the answer to be 3.29 X 10^-19 J.

what did i do wrong ?
Answered by DrBob222
I have 3.28 x 10^-19 J.
I am using 6.626E-34 for h, 3 x 10^8 m/s for c and 606 x 10^-9 m for wavelength.
