Answer:
[tex]\lambda=25\times 10^6\ m[/tex]
Explanation:
Given that,
The frequency of the light wave, f = 12 Hz
We need to its wavelength. The wavelength of the wave can be calculated as follows :
[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{12}\\\\\lambda=25\times 10^6\ m[/tex]
So, the wavelength of the light wave is equal to [tex]25\times 10^6\ m[/tex].
