Calculate the angle at which first order reflection will occur in an X-ray spectrometer when X-rays of wavelength `1.54Å` are diffracted by the atoms of a crystal given that interplanar distance is `0.04Å`.

To calculate the angle at which first order reflection will occur in an X-ray spectrometer, we will use Bragg's Law, which is given by the equation: \[ n\lambda = 2d \sin \theta \] Where: - \( n \) = order of reflection (for first order, \( n = 1 \)) - \( \lambda \) = wavelength of the X-rays - \( d \) = interplanar distance ...
