MCQ
Frequency of a wave is $6 \times {10^{15}}Hz.$ The wave is
- ARadiowave
- BMicrowave
- C$X-$ ray
- ✓None of these
✓
Answer
Correct option: D.
None of these
d
$f=6 \times 10^{15}\,Hz$
$f=6 \times 10^{15}\,Hz$
$\lambda=\frac{c}{f}=\frac{3 \times 10^8}{6 \times 10^{15}}\,m$
$m \lambda=5 \times 10^{-8}\,m$
for, $10^{-8} m < \lambda < 10^{-11} m$ it is $x$-ray
