Answer 2

Answer:

3.6×10^-19 J

Explanation:

as we know,,

the formula for energy of photon in terms of wavelength is,, E = hc/lambda

where, E = energy of photon

h = Planck's constant =

= 6.63×10^-34 Js

c = speed of light

= 3×10^8 m/s

and lambda = wavelength

so,,

E = [6.63×10^-34 Js×3×10^8 m/s]/5500×10^-10m

= [0.36×10^-26]/10^-8

= 0.36×10^-18

= 3.6×10^-19 J

plz check the answer....if it wrong u can report
