A radio station broadcasts at a frequency of 400 kHz. If the speed of the wave is 3.0 ×10\(^{-8}\)ms\(^{-1}\), calculate the wavelength of the radio wave.
a
1.3 × 102m
b
3.0 × 102m
c
2.4 × 102m
d
5.0 × 102m
e
7.5 × 10-14m

Can someone please confirm if im correct, thanks.
Given that wavelength(lambda) is equal to velocity(speed) divided by frequency (f)
Thus,
wavelength = (3.0 ×10^-8) ÷ (400 × 1000)...because of the kilo,which means a thousand
If you divide as usual you should get 7.5×10^-2
I dont think E is correct but maybe i made a mistake
let me know
