A radio can tune into any station in the `7.5 MHz` to `12 MHz` band. What is the corresponding wavelength of band?

Explanation

For frequency ,` V_1 = 7.5 MHz = 7.5 xx 10^6 HZ `
wavelength is given by
` lamda_1 = ( c )/( v_1 ) = ( 3 xx 10 ^8 ) /( 7.5 xx 10^6 ) = 40 m`
for frequency `, V_2 = 12 MHz = 12 xx 10 ^6 Hz `
` lamda _2 = (C )/( v_2) = ( 3xx 10^8 ) /( 12 xx 10^6 ) = 25 m`
so the wavelength band `: 40 m " to " 25 m.`
