Let the frequency be 'f' and wavelength be 'w'
[tex] f\alpha \frac{1}{w} [/tex]
[tex] f = \frac{k}{w} [/tex] , [tex] k\neq 0 [/tex]
w= 100 m and f = 3,000 kilohertz
Plug in the above values to find k
3000 = [tex]\frac{k}{100} [/tex]
To find k, multiply both side by 100
3000(100) = k
k = 300,000
So equation becomes,
[tex] f = \frac{300,000}{w} [/tex]
w= ? f = 500 kilohertz
500 = [tex] \frac{300,000}{w} [/tex]
w = [tex] \frac{300,000}{500} [/tex]
w = 600 m
