In order to find the wavelength of the X-rays diffracted at this angle, we can use Bragg's law:

nλ = 2dsinθ

where n is the order of diffraction, λ is the wavelength of the X-rays, d is the spacing between the crystal planes, and θ is the angle of diffraction.

Since we are given the angle of diffraction (θ = 11.8°) and the order of diffraction (n = 1), we can rearrange the equation to solve for λ:

λ = 2dsinθ / n

Let's assume we know the spacing between the crystal planes (d). If we substitute the given values into the equation, we can find the wavelength of the X-rays.
