A) \[6\times {{10}^{-12}}\operatorname{m}\]
B) \[3\times {{10}^{-8}}\operatorname{m}\]
C) \[1.6\times {{10}^{11}}\operatorname{m}\]
D) \[15\times {{10}^{27}}\operatorname{m}\]
Correct Answer: A
Solution :
Option [a] is correct. Explanation: \[\lambda =\operatorname{v}/c=\frac{3\times {{10}^{8}}}{5\times {{10}^{19}}}=6\times {{10}^{-12}}\operatorname{m}\]
