When an x-ray beam is scattered off the planes of a crystal, the scattered beam creates an interference pattern. This phenomenon is called Bragg scattering. For an observer to measure an interference maximum, two conditions have to be satisfied: a). An x-ray beam with wavelength 0.120 nm is directed at a crystal. As the angle of incidence increases, you observe the first strong interference maximum at an angle 23.0 ∘. What is the spacing d between the planes of the...
An x-ray beam with wavelength 0.300 nm is directed at a crystal. As the angle of incidence increases, you observe the first strong interference maximum at an angle 24.5 degree. What is the spacing d between the planes of the crystal? Express your answer in nanometers to four significant figures. d = _____nm Find angle theta_2 at which you will find a second maximum. Express your answer in degrees to four significant figures. theta_2 = _____
