Questions
If the energy of a photon corresponding to a wavelength of 6000 is 3.32 x10-19 joule, the
photon energy (in joule) for a wavelength of 4000 will be
a
1.11 x10-19
b
2.22 x10-19
c
4.44 x 10-19
d
4.98 x 10 -19
detailed solution
Correct option is D
we know that E=hc/λE1=hcλ1 and E2=hcλ2 or E2=E1×λ1λ2 =3⋅32×10−1960004000=3⋅32×10−19(3/2) =4.98×10−19 jouleTalk to our academic expert!
