Bragg's X- rays diffraction studees are successful when

X-rays can be used to study crystal structure, if the wavelength lies in the range

Bragg reflection can occur only when gamma le 2d .

Bragg reflection can occur only when gamma le 2d .

The diffraction of crystal of Ba with X-ray of wavelength 2.29Å gives a first order reflection at 27^(@)8' . What is the distance between the diffracted patterns ?
