MCQ
Find the $\%$ difference (approximate) in deBorglie wavelength if the temperature of gas become double ............. $\%$
- ✓$30$
- B$40$
- C$50$
- D$100$
$\Rightarrow \lambda \propto \frac{1}{\sqrt{\mathrm{T}}} \Rightarrow \lambda_{2}=\frac{\lambda_{1}}{\sqrt{2}}$
of charge $=\frac{f-i}{\ell} \times 100=\frac{\frac{\lambda_{1}}{\sqrt{2}}-\lambda_{1}}{\lambda_{1}} \times 100$
$=\frac{\frac{1}{\sqrt{2}}-1}{1} \times 100=30 \%$
