What is the wavelength of light associated with the radiation of 7.26 x 10-19 J/photon? (h = 6.63 x 10-34 J • s)

Answer 1

E = hc/wavelength.
Solve for wavelength.

Answer 2

Solve this equation for wavelength:
E = 7.26 x 10-19 J = h c /(wavelength)

c is the speed of light, 3.00*10^8 m/s

Answer 3

Thanks guys, brain fart i guess. I wasn't putting together the E=7.26e-19

Answer 4

724nm

Answer 5

274nm (sorry)
