A particular green LED emits light of wavelength 5490, Å, the energy bandgap of the semiconductor material used there is .. h = 6.6 x 10-34 J sec.
2.26 eV
1.98 eV
1.17 eV
0.74 eV
Correct answer is A
From Plank equation, E = hc/λ joule
to convert it into electron volt it will be divided by 1.6 x 10-19.
