50 m

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Given : Frequency $f_1=6 \mathrm{MHz}$ Frequency $\mathrm{f}_2=10 \mathrm{MHz}$ $$ \begin{aligned} & \lambda_1=\frac{c}{f_1} \\ & \lambda_2=\frac{c}{f_2} \end{aligned} $$ Wavelength bandwidth $=\lambda_2-\lambda_1=20 \mathrm{~m}$
