$f equals 3 space MHz equals 3 cross times 10 to the power of 6 space Hz lambda equals c over f equals fraction numerator 3 cross times 10 to the power of 8 over denominator 3 cross times 10 to the power of 6 end fraction equals 100 space straight m$

$f equals 5 space MHz equals 5 cross times 10 to the power of 6 space Hz lambda equals c over f equals fraction numerator 3 cross times 10 to the power of 8 over denominator 5 cross times 10 to the power of 6 end fraction equals 60 space straight m$

$f equals 15 space MHz equals 15 cross times 10 to the power of 6 space Hz lambda equals c over f equals fraction numerator 3 cross times 10 to the power of 8 over denominator 15 cross times 10 to the power of 6 end fraction equals 20 space straight m$

$f equals 20 space MHz equals 20 cross times 10 to the power of 6 space Hz lambda equals c over f equals fraction numerator 3 cross times 10 to the power of 8 over denominator 20 cross times 10 to the power of 6 end fraction equals 15 space straight m$
