Answer
Please see the work below.
Work Step by Step
We know that
(a) $\lambda=\frac{v}{f}$
We plug in the known values to obtain:
$\lambda=\frac{3\times 10^8}{1.0\times 10^6}=300m$
(b) $\lambda=\frac{v}{f}$
We plug in the known values to obtain:
$\lambda=\frac{3\times 10^8}{190\times 10^6}=1.6m$
(c) $\lambda=\frac{v}{f}$
We plug in the known values to obtain:
$\lambda=\frac{3\times 10^8}{10\times 10^9}=0.03m$
(d) $\lambda=\frac{v}{f}$
We plug in the known values to obtain:
$\lambda=\frac{3\times 10^8}{4\times 10^{13}}=7.5\mu m$
(e) $\lambda=\frac{v}{f}$
We plug in the known values to obtain:
$\lambda=\frac{3\times 10^8}{6.0\times 10^{14}}=500nm$
(f) $\lambda=\frac{v}{f}$
We plug in the known values to obtain:
$\lambda=\frac{3\times 10^8}{1.0\times 10^{18}}=0.30nm$
