A) \[\operatorname{K} + {{E}_{o}}\]
B) 2K
C) K
D) \[\operatorname{K}+hv\]
Correct Answer: D
Solution :
using Einstein equation of photoelectric effect \[\operatorname{W}={{\phi }_{o}}+KE\] \[hv={{\phi }_{o}}+K\] \[{{\phi }_{o}}=hv-K\] ?.(1) If frequency of incident is double \[2hv={{\phi }_{o}}+{{K}_{1}}\] .?(2) By using equation \[2hv=(hv-K)+{{K}_{}}\left( {{\phi }_{o}}=hv-K \right)\] \[{{\operatorname{K}}_{l}}=hv+K\]You need to login to perform this action.
