<u>Answer:</u> The wavelength for X-rays with the given frequency is 
<u>Step-by-step explanation:</u>
To calculate the wavelength of light, we use the equation:

where,
= wavelength of the light
c = speed of light = 
= frequency of light = 
Putting the values in above equation, we get:

Hence, the wavelength for X-rays with the given frequency is
