X rays that have wavelengths of 0.125 nm are scattered off free electrons at an angle of 45.0∘∘.

1) Calculate the wavelength of the scattered electromagnetic radiation. (Express your answer to four significant figures.)

answer is: 125 nm

2) Calculate the fractional wavelength change (Δλ/λi=(λf−λi)/λiΔλ/λi=(λf−λi)/λi) for the scattered X rays. (Express your answer to three significant figures.)

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: The angle of incidence has to be equal to the angle of reflection. The difference in the beam's path from a source to an observer for neighboring planes has to be equal to an integer multiple of the wavelength; that is,...
