Following is the text part of the solution. Please see the attached file for complete solution. Equations, diagrams, graphs and special characters will not appear correctly here. Thank you for using Brainmass.
λf - λi = (h/mc) (1 - cos theta)
λi = 1.5 x 10^-12 m
λf = λi + (h/mc) (1 - cos theta)
λf = 1.5 x 10^-12 + (2.43x10^-12) (1 - cos 25) = 1.728 x 10^-12 m
