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: $\lambda=\frac{3\times 10^8}{1.0\times 10^{18}}=0.30nm$
