When discussing Bragg scattering we showed that constructive interference between waves reflecting from Bragg planes occurs when Ar = 2d sin(0) = nλ where Ar was the path length difference, d was the spacing between Bragg planes, the angle between the incident motion (light ray or particle direction) and the Bragg plane, n an integer, and λ the wavelength of the light or deBroglie wave. When discussing the diffraction from a single crystal of Ni we expressed this condition for constructive interference as D sin(ø) = nλ, where D was the spacing between Ni atoms, and was the angle between particles shot perpendicular to a face of the Ni crystal and their reflection to a detector. The relation Φ between the angles is: 0 = and between the distances is d = D sin(). 2 (a) Using identity, e¹A cos(A) e¹A+e-iA 2 cos(A) + i sin(A), prove that sin(A) = where i = √-1 is an imaginary number. = = e¹A-e-iA 2i - (b) Using the identities from part (a) prove that sin(A - B) = sin(A) cos(B) – cos(A)…arrow_forward

Lyman series n-5 (a) (b) e These pictures refer to the energy levels of a hydrogen atom. You can find the error in both parts, (a) and (b). The arrows labeled "emission" in (a), and all the arrows in (b), indicate a transition in which an electron jumps from a higher- energy state to a lower-energy state. The different "series" of emission lines are characterized by the index n of the low- energy state in which the electron ends up. In particular, the Lyman series consists of all transitions that end up in the n=1 energy level, with an initial energy level that corresponds to the label n = 2, 3, 4, 5, etc. One of these values of n is not shown as an arrow in the Lyman emission series in figures (a) or (b). This is a significant error because that particular spectral line is very important in astronomy.
