Answer: The wavelength of radiation is [tex]4.34\times 10^{21}m[/tex]
Explanation:
The relationship between wavelength of light and frequency of light is given by the equation:
[tex]\nu=\frac{c}{\lambda}[/tex]
where,
[tex]\nu[/tex] = frequency of radiation = [tex]6.912\times 10^{-14}s^{-1}[/tex]
c = speed of light = [tex]3\times 10^8m/s[/tex]
[tex]\lambda[/tex] = wavelength of radiation = ?
Putting values in above equation, we get:
[tex]6.912\times 10^{-14}s^{-1}=\frac{3\times 10^8m/s}{\lambda}\\\\\lambda=4.34\times 10^{21}m[/tex]
Hence, the wavelength of radiation is [tex]4.34\times 10^{21}m[/tex]
