A) \[\frac{\lambda }{2}\]
B) \[\lambda \]
C) \[2\lambda \]
D) None of these
Correct Answer: A
Solution :
de-Broglie wavelength \[\lambda \propto \frac{1}{\sqrt{T}}\] \[\frac{{{\lambda }_{1}}}{{{\lambda }_{2}}}=\sqrt{\frac{{{T}_{2}}}{{{T}_{1}}}}\] \[\frac{{{\lambda }_{1}}}{{{\lambda }_{2}}}=\sqrt{\frac{273+927}{273+27}}=\sqrt{\frac{1200}{300}=2}\] or \[{{\lambda }_{2}}=\frac{\lambda }{2}\]You need to login to perform this action.
