MCQ
Communication on ground is through electromagnetic waves of wavelength
- Alarger than $600\, m$
- Bbetween $200$ and $600\, m$
- Cbetween $1$ and $5\, m$
- ✓between $10^{-3}$ and $0.1$
✓
Answer
Correct option: D.
between $10^{-3}$ and $0.1$
d
The required wavelength should be from $10^{-3}\, \mathrm{m}$ to $0.1\, \mathrm{m}$
The required wavelength should be from $10^{-3}\, \mathrm{m}$ to $0.1\, \mathrm{m}$
$\Rightarrow I_{e}=\frac{100}{90} \times 10 \,\mathrm{mA}=11.1\, \mathrm{mA}$
