A) 1 eV
B) 1.6eV
C) 3.2 eV
D) 7eV
Correct Answer: B
Solution :
Energy of photon,\[E=\frac{12375}{\lambda (in{\AA})}eV\] For red light the wavelength is maximum. \[\because \] \[{{\lambda }_{R}}=7900{\AA}\] \[\therefore \] \[E=\frac{12375}{7900}eV\] \[=1.56\,eV\] \[\simeq 1.6\,eV\]You need to login to perform this action.
