QJEEM22Ph4dec: JEE Main 2022 Physics - Class 12 JEEM22Ph4dec Solution: A radio can tune to any station in to band. The value of…

${v_1} = 6 \times {10^6}$ Hz

$\Rightarrow {\lambda _1} = {{3 \times {{10}^8}} \over {6 \times {{10}^6}}} = 50$ m

${v_2} = 10 \times {10^6}$ Hz

$\Rightarrow {\lambda _2} = {{3 \times {{10}^8}} \over {10 \times {{10}^6}}} = 30$ m

$\Rightarrow$ Wavelength band with

$= |{\lambda _1} - {\lambda _2}| = 20$ m
