A) infrared
B) violet
C) red
D) blue
Correct Answer: B
Solution :
Energy of photon \[E=\frac{hc}{\lambda }\] where h and c are constant. \[\therefore \] \[E\propto \frac{1}{\lambda }\] As \[{{\lambda }_{\operatorname{infra}}}>{{\lambda }_{R}}>{{\lambda }_{B}}>{{\lambda }_{V}}\] Energy of photon will be maximum for violet colour.
