MCQ
The de-Broglie wavelength of a particle with mass $1\,gm$ and velocity $100\,m/\sec $ is
- ✓$6.63 \times {10^{ - 33}}\,m$
- B$6.63 \times {10^{ - 34}}\,m$
- C$6.63 \times {10^{ - 35}}\,m$
- D$6.65 \times {10^{ - 35}}\,m$
✓
Answer
Correct option: A.
$6.63 \times {10^{ - 33}}\,m$
a
(a) $\lambda = \frac{h}{{mv}} = \frac{{6.63 \times {{10}^{ - 34}}}}{{{{10}^{ - 3}} \times 100}} = 6.63 \times {10^{ - 33}}\,m$
(a) $\lambda = \frac{h}{{mv}} = \frac{{6.63 \times {{10}^{ - 34}}}}{{{{10}^{ - 3}} \times 100}} = 6.63 \times {10^{ - 33}}\,m$
