A) \[{{10}^{10}}\] per metre
B) \[{{10}^{7}}\] per metre
C) \[{{10}^{4}}\] per metre
D) \[{{10}^{-7}}\] per metre
Correct Answer: B
Solution :
Rydberg constant \[R=-\frac{E}{ch}\] \[=-\frac{13.6\times 1.6\times {{10}^{-19}}}{3\times {{10}^{8}}\times 6.6\times {{10}^{-34}}}\] \[={{10}^{7}}\]per metreYou need to login to perform this action.
