Vijayawada FM radio station broadcasts at frequency of 103.4 MHz. The wavelength of the corresponding radio waves (in $\mathrm{m}$ ) is
  1. 2.90
  2. 29.0
  3. 9.20
  4. 92.0

Solution

$\lambda=\frac{\mathrm{c}}{\mathrm{v}}=\frac{3 \times 10^8 \mathrm{~ms}^{-1}}{1.034 \times 10^8 \mathrm{~s}^{-1}} \cong 2.90 \mathrm{~m}$
