A) \[0.207\times {{10}^{-5}}m\]
B) \[2.07\times {{10}^{-5}}m\]
C) \[20.7\times {{10}^{-5}}m\]
D) \[2075\times {{10}^{-5}}m\]
Correct Answer: B
Solution :
[b] \[\lambda =\frac{hc}{E}\] \[=\frac{6.62\times {{10}^{-34}}\times 3\times {{10}^{8}}}{(60\times {{10}^{-3}}\times 1.6\times {{10}^{-19}})}=2.07\times {{10}^{-5}}m\]You need to login to perform this action.
