Answer:
[tex]\lambda=10^{26}\ m[/tex]
Explanation:
It is given that,
The frequency of the electromagnetic radiation, [tex]\lambda=3\times 10^{-18}\ Hz[/tex]
We need to find the frequency of the electromagnetic radiation. The relation between the frequency and wavelength is given by :
[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{3\times 10^{-18}}\\\\=10^{26}\ m[/tex]
So, the wavelength of the electromagnetic radiation is [tex]10^{26}\ m[/tex].
