MCQ
$X-$ rays of $\lambda = 1\,{Å}$ have frequency
- A$3 \times {10^8}\,Hz$
- ✓$3 \times {10^{18}}\,Hz$
- C$3 \times {10^{10}}\,Hz$
- D$3 \times {10^{15}}\,Hz$
✓
Answer
Correct option: B.
$3 \times {10^{18}}\,Hz$
b
(b) $\nu \, = \frac{c}{\lambda } = \frac{{3 \times {{10}^8}}}{{1 \times {{10}^{ - 10}}}} = 3 \times {10^{18}}Hz$
(b) $\nu \, = \frac{c}{\lambda } = \frac{{3 \times {{10}^8}}}{{1 \times {{10}^{ - 10}}}} = 3 \times {10^{18}}Hz$
