Explanation:
It is known that relation between wavelength and frequency is as follows.

where,
= wavelength
c = speed of light = 
[/tex]\nu[/tex] = frequency
It is given that frequency is
. Hence, putting this value into the above formula and calculate the wavelength as follows.


= 
or, = 
Thus, we can conclude that wavelength of given radiation is
.
