Answer
(a) 2.99 m
(b) $2.80\times10^{2}\,m$
(c) 0.359 m
Work Step by Step
Using the relation $\lambda=\frac{c}{\nu}$ where $c$ is the speed of light, we have
(a) $\lambda= \frac{3.00\times10^{8}\,m/s}{100.2\,MHz}$
$=\frac{3.00\times10^{8}\,m/s}{100.2\times10^{6}\,s^{-1}}$
$=2.99\,m$
(b) $\lambda= \frac{3.00\times10^{8}\,m/s}{1070\,kHz}$
$=\frac{3.00\times10^{8}\,m/s}{1070\times10^{3}\,s^{-1}}$
$=2.80\times10^{2}\,m$
(c) $\lambda= \frac{3.00\times10^{8}\,m/s}{835.6\,MHz}$
$=\frac{3.00\times10^{8}\,m/s}{835.6\times10^{6}\,s^{-1}}$
$=0.359\,m$
